• This episode introduces the subplot of Gibbs building his boat with a lack of power tools, which he continues working on throughout this and the next three seasons.
• The background given for Abby regarding her interest in forensics is the same as Pauley's: living near a wrecking yard and being intrigued by the cause and effect of the wrecks.
• When Gibbs is checking different parachutes, Tony asks what he is looking for. Gibbs replies, "A screwed pooch." Screw the pooch is military slang for badly messing something up.
• Several characters get their names from crew members: Sarah Schaefer (Construction Coordinator, Thom Schaefer) Sgt. Gregory Nutt (Transportation Coordinator, Greg Nutt) Cpl. Paul Dafelmair (Costume Supervisor, Paul Dafelmair).

• In the elevator, Tony said something to Gibbs in sign language that was never voiced. He signed, "I see."

• While the reporter is filming her segment about what really happened, right as she is signing off, "This is Diane Fontaine, WXEK News," her microphone is facing so that you can see the logo "WXEK". In the next shot, they zoom in closer on her, and the microphone shows a big "19".

• About 41 1/2 minutes into the show, while the NCIS team is packing up, you can hear "RM2 Thomas report to the ?? Galley" passed over the 1MC (shipboard general announcement system). The Navy did away with RMs about 3 years ago.

• After the final intermission, the scene opens up with the port (left) side of the the Forrest except for the fact that the number showing is now 12 and not 51.
• Super Cell Phones? The agents are constantly talking to each other from inside the ship when out at sea. Ships made of steel or aluminum wreak havoc on cell phones. Setting next to the pier you'd be lucky to find a spot where a cell phone would work inside a ship. Even only a mile or two off shore you'd have to go topside to talk on a cell-phone.
• When we see Tony take off the carrier, the helicopter he's on has the number 406. When we next see the helicopter landing in Puerto Rico, the number is now 420.
• The nurse says that the dead officer was obsessed with his mysterious friend. Later, she tells Kate that he only talked about him once.

• This is the first episode when Gibbs hits the back of Tony's head.
• When Tony, Abby, and Gibbs are examining the cargo pod, Abby says something to Gibbs in sign language that is never voiced. She signs, "Tony's weird."

• Before joining NCIS, Tony worked for the Peoria, Philadelphia, and finally Baltimore police departments.
• Gibbs is wearing a Property of Hoover Police Department t-shirt in his basement. This is a department in Hoover, Alabama.
• About 27 minutes in: when Kate and Tony are disagreeing on how to get to 3-79-9-A.. When they are talking to Abby in the scene before, Kate is wearing a red top and green jacket. They exit into the corridor and continue with their bickering (Kate in the same dress mode, she just puts on a jacket) and then they go their separate ways. However when the scene changes, cutting to Kate walking down another corridor, (turning slightly to avoid a petty officer), she is now wearing the same purple turtle neck that was used earlier (presumably day one). Cut to Tony going up stairs and then back to Kate, still in the purple turtle neck. Cut to Tony 'Skipping' over a knee-knocker, thinking he has got there first. (AT 3-58-9-A) He opens the door, then it is cut to Kate.. now wearing the original red top and green jacket, flashing her credentials to the officer.

• Stan asks Gibbs for help while working on board USS Enterprise. When the COD lands on the carrier, it is not CVN 65 - Enterprise, but CVN 74 - John C Stennis. The Stennis is the carrier shown at the start of the season 1 titles. Also while walking through a hangar bay 13 minutes into the episode, an aircraft behind them has the markings of CVN 70 - USS Carl Vinson.
• When the helicopter is rescuing the crew of the yacht you see the shoulder boards of an officer in the doorway. The shoulder boards have a loop at the top, as used by the Royal Navy.
• In addition to the shoulder boards, when the shot focuses on the air rescue team retrieving the capsized yachtsmen, on the shoulder of one of the rescuers there is a blatantly obvious Australian flag. I must admit I never knew the HMAS Perth was part of the USS fleet.

• Whilst interviewing the first Petty Officer, Gibbs and Todd note that he was lying because his eyes looked to his left. This is a famous part of Neuro-Linguisting Programming, but they get it wrong. NLP is based on looking at a person - if their eyes go to their left the observer would see them going to the right, which would mean a truth rather than a lie. (NLP is based off a normal right handed person, if he was left handed the cues would be opposite. there is never a clue as to what the petty officer was.)
• In an interview, Michael Weatherly said that while throwing a rock through the window was scripted, the running and football commentary was just improvising on his part. He claims this was the start of his ad-libbing in the series.
• Note McGee's tie. He wears the same tie in every season 1 episode until he gets his 'stripes' in season 2. Also, McGee holds his gun in his right hand this episode, all other episodes, he uses his left.

• McGee asks Tony about what Abby looks like. McGee had seen Abby in the video conference that Abby & Ducky had with Gibbs. He was standing beside Gibbs and had to have seen her.

• Tony wakes up screaming because there was a large lizard on the pillow next to him. Todd and Gibbs enter the room in their sleeping clothes. Kate's wearing a USC jersey. This is a little joke on Mark Harmon, since he played football for UCLA, a crosstown rival. Which explains the little smile she gives to Gibbs when he walks past her. On ET, Sasha admitted she got the jersey as a joke on Mark Harmon.

• When Tony goes back to talking to the bartender about movies he mentions, "So Jack Palance shoots Elijah Wood..." According to www.imdb.com, Jack Palance and Elijah Wood have not starred together in anything.
  
  The barkeeper was talking about how Jack Palance shot Elisha Cook, and afterwards Tony mixes up Cook and Wood. This confirms what the bartender said about young people not knowing anything about good,old movies. Thats the reason the bartender rolls his eyes and walks away.
• In this episode people make several references to the movie The Maltese Falcon around Tony, but he doesn't get them. However, later in the series, Tony is a movie buff with knowledge of all genre of movies. How would he not know The Maltese Falcon in this episode?
• When Abby is sending an e-mail to Gibbs, she types in bds28338@navy.mil.gov, a navy e-mail would be just navy.mil (or something preceding it) but no ending .gov, such as nrl.navy.mil

• If you look quickly enough while Gibbs types his password into Tony's computer at the start of the episode, we can see that Gibbs' NCIS clearance userID is 'lj_gibbs_NCIS'.
• In this episode, Kate makes a joke about how many times Gibbs has been married. Gibbs corrects her and says he's only been married 3 times instead of 4, which isn't true. In the third season we find out he has been married 4 times and 3 of them ended in divorce. His first wife and his daughter were killed.

• When Major O'Donnell and Sarah Kidwell enter the squad room and tell the team that they recorded her husband's phone call, Tony wears a blue shirt. When they go down to the lab to play the recording, he is wearing a dark sweater.
• Ground-penetrating radar cannot transmit through a metallic coffin. It uses microwave radiation, which can penetrate many things, including a wooden coffin or the concrete chest many states require for burial, but not through a thin sheet of metal (even goldleaf would cause major imaging problems).

• Although the character of 'Dr. Stephen Bauer' is supposed to be German the actor who portrays him speaks German with a strong Dutch accent.
• The German translation of explosive maker Suzzanna McNeil uses makes no sense: In "explosiver Hersteller" explosiver translates to the adjective explosive. The correct translation would be "Sprengstoff Hersteller".
• When Tony recites the contents of the liquor cabinet at The Jackson Hotel, he imitates Sean Connery for the first time when saying Bombay Sapphire.
• Actually, although you almost have to use freeze frame to see it, Gibbs has a bruise on his right cheek. I couldn't get a clear look at Tony's face to tell if there was some mark on his lip, but it seemed like there was. Kate was closer to the bomb blast and was moving forward. Plus, you can see a chair flying toward the agents, almost right at Kate.

• Why is Kate the only one injured in the explosion? Tony and Gibbs were only a few feet away from her, yet neither of them has a scratch on them.

• In the scene where Tony is working out his forearm--he enters the room with his sleeves rolled up just below his elbow. When he stops to talk to Abby, his sleeves are rolled up to his biceps. For the rest of the scene, his sleeves are rolled to his forearms again.
• When Tony is interviewing the Naval base operator, his hair is kind of windblown and relaxed from air-drying after getting wet in the ocean. Later, when he's working with McGee to track down the phone number, he's got his hair slicked back. After that, when he meets Gibbs and Kate outside, his hair is all windblown and relaxed again.

• Bonnie Bartlett co-starred with Mark Harmon on the 80s medical drama "St. Elsewhere." Mark Harmon played Dr. Bobby Caldwell and Bonnie Bartlett played Ellen Craig.
• Somehow Gibbs goes from rubbing his head like he has a headache to leaning on his hand in less than a second. You see it in the scene where he's talking to Ducky in the squad room.

• The standard operating procedure is that after any law enforcement officer fires his gun, there has to be an investigation as to the shooting. That being the case, even though the FBI wanted credit for solving the crime, why bother telling Tony to leave? Since he was the shooter, now matter what, everyone's going to know that NCIS took care of the problem.
• In this episode, USMC Gunnery Sergeant Carlos N. Hathcock II "White Feather" is mentioned. However, they said he had 39 kills when he really has 93 confirmed kills with over 300 possible.

• It was a bit coincidental to have the bullet lose velocity at exactly the right moment it entered the doll's head, but stranger things have happened, and it did give us a very cool scene with Abby, so it's entirely excused.
• Tony must be a really bad shot to have hit a water bottle a couple of metres away from the sniper. (Shooting a handgun accurately is much harder than it looks and what most television shows portray, it's hard to put all shots on target under fire, and Tony was closer to 10 meters away from his target.)

• When Kate is amazed at Tony's over the shoulder shot at the trash can and wonders how he did it, he states that he was first team varsity at Ohio State.
• When the team is inspecting the very first victim, the sheriff says he was found with no clothes on. When pictures are taken of his backside, this appears to be the case. However, when they roll the body over to look at the front, you can see the nude-colored underwear on the body that would be necessary for modesty's sake.
• Among the lunch boxes show in the home of the victim, you can see ones for "Magnum P.I.", "Airwolf" and "Quantum Leap;" all shows created by Donald P. Bellisario.
• One character mentions another character had a very successful grandfather who made his fortune importing the first Swiss Army Knives in to the US. In real life, it was series costar Michael Weatherly's father, Michael Weatherly Sr., who made a fortune bringing the first Swiss Army Knives in to the US.

• Gibbs uses OnStar to track the location of Laura Seeger's twin, but she drives a Jeep Cherokee, a model which has never been equipped with OnStar.

• When DiNozzo returns from the store, he mentions he has Darjeeling tea from northwest Kashmir. Darjeeling tea is grown in Darjeeling, India, which is in the West Bengal state east of Nepal. Jammu-Kashmir is in the extreme north of India, 1,000 kilometres away to the west.

• The terrorist said he would shoot Gerald in his ball and socket joints if Ducky lied. After he shot Gerald in the shoulder, he threatened to shoot Gerald in the knee. The knee is a hinge joint, not a ball and socket joint. (Actually the knee is a ball and socket joint. The only reason it seems like a hinge joint is because the knee cap stops it from bending forwards.)

• In one scene the car door to the Dodge that Gibbs was just driving is open then closed in the next angle. This takes place at the warehouse where the party was.

• When Ducky is describing the injuries of the man run over to Gibbs, he says that he has a broken "tibia and fibia", however the correct name for the second bone is "fibula".
• When Gibbs turns the car around suddenly, you hear a car horn, but the road is empty.
• When the browser returns the hits from Google, the address bar is empty. As of now, there no known browser that deletes the URL from the address bar after you click on the Google Search button, nor would that be logical.
• When Tony searches Google for "Bartex Corporation", he enters that phrase directly into the search line. However, upon termination of the search, we see apparently Tony searched "Bartex", not "Bartex Corporation". Google wouldn't filter out the word Corporation.
• MCPO Nutter's Sable has California Tags in a glimpse or two when they trap him at the Bartex place.

• The episode, with the "The Fugitive" and "US Marshalls" theme portraying the manhunt for an innocent man, never bothered to show any physical evidence to suggest that anyone other had done the crime, only that Curtain was hellbent to exact revenge on her wife's lover, though the NCIS team seemed pretty convinced he was innocent.

• Victims died from broken necks supposedly administered by strong skilled "man" yet perp was slight women not likely to have done it. If it was her husband that was not clear and if so why?
• X-Rays of the victims broken neck keep switching places as Ducky and Gibbs talk.
• Tony says the phone records are from UpfrontPhone.com but the paper he hands Gibbs says "Easyphone dot com" at the top in the close-up shot.
• It is the MISSOURI River, not the Mississippi River, that is between Missouri and Kansas. Levenworth, KS is across from the upper part of Kansas City, Mo (across from the KCI Airport) and St. Joseph is further north. It is impossible to swim across due to the heavy undercurrent, and speed of the Missouri River, he would have died, or been swept down stream.

• McGee discovers an oak tree of a specific type is planted outside Amanda's house. He refers to it as Quercus Virginia. The actual name should be Quercus virginiana.
• During the autopsy, Ducky finds a memory card that was swallowed by the deceased. The memory card that is shown is an SD Digital type card, very small and can be swallowed. However, we see in the next scene that NCIS issue cameras are Nikon D100's. The D100 accepts only the professional-grade and higher capacity compact flash or Microdrives which are too big to be swallowed. The memory card found could not have been used in an NCIS camera.

• When Ducky walks back to Pacci's body after talking to Gibbs about the foreign object in the x-ray and says, "That would be my guess, Jethro," you can see the abdomen rise as the actor inhales.
• When we first see Abby talking to Gibbs, watch right after she says "The gun's a virgin." Gibbs turns to leave, and behind him you can see part of a man's shoulder and torso. This is obviously a crew person, as no one else is in the room at the time.

• Abby: All I drank was Red Bull!
  Kate: How many?
  Abby: 18.
  
  According to the warning label on the back of Red Bull cans, no more then 2 cans (500mL) should be consumed per day.
  
  If more then 5 cans are consumed (1.25L) then possible side affects include nausea, diarrhoea, stomach pains, gas, light green urine color, sleeplessness and/or fatigue when caffeine effect wears off.
• During the episode, Gibbs tells Tony to "watch his six" meaning be careful. Six is military slang for tail because aviators refer to their position in reference to the face of a clock. Twelve o'clock is directly in front of you, and six o'clock is directly behind you.
• "Extra" host Dayna Devon popped up in cameos on more than a dozen shows all around the dial in 2004 including this NCIS episode. But wasn't just for fun -- it was also for charity. Dayna has donated all of her acting fees from Dayna TV to the Elizabeth Glaser Pediatric AIDS Foundation, which helps children infected with the AIDS virus. All those zany, short-lived cameos raised $10,000 for the Foundation.

• When Tony leaves the bar and phones Gibbs, Gibbs has on a full set of latex gloves. He takes off the left one, but keeps the right one on as he answers the phone. For most of the conversation, he has the glove on, then suddenly it's gone, with no indication that he had the time or inclination to take it off.
• The entrance to the sewers says Manassas County, but Manassas is a city in Virginia.
• When Kate and Tony present the results of their all-nighter to Gibbs and Tony tries to convince Gibbs to let him shadow Sacco. First, we see Tony sitting at his desk slightly turned to the side to face Gibbs, then Gibbs steps behind the desk to get himself another slice of pizza and Tony sits straight at his desk. And rolls his eyes at Gibbs, which is a really cute scene, but kind of ruined because in the next shot, he again sits facing Gibbs.

• This is the second time in the series that Michael Weatherly's character, Tony has gone undercover with the name "Gus". Another point would be that Michael Weatherly has a son named August, nicknamed "Gus".
• Very few UK universities or schools (if any), produce a US style year book, let alone have an electronic record of year book style photographs.

• When Tony is talking to ATF Agent Stone, the camera pans around his head. On the first pan, there is no earring. On the second, there is an earring in his left ear.

• If Johnson was such a religious man - and Catholic, as we have seen - then why would he have committed suicide? It's been stated in the show before ("The Immortals," episode 1.04) that suicide is a mortal sin, and a *huge* deal within the Catholic community. (Homosexuality is also a mortal sin in many Christian groups, he acted on his homosexual feelings, and the guilt he felt after that might have caused him to kill himself. This is sadly not as uncommon a reaction as one would like to hope within religious people who find out they are homosexual.)
• In this episode Ducky brought the team ice-cream when they were working late at night as to why the D-link had failed, and when asked why he wasn't asleep, he said it was because of his noisy upstairs neighbours - yet in a later episode we discover he lives in a detached house in a secluded area, i.e. where were the upstairs neighbours.
• Note to above paragraph: I do not think Ducky ever said "upstairs" neighbors -- just that his neighbors were keeping him awake. I'll rewatch the DVD soon and update my note.
• Update: Gibbs, Kate, and Tony are working late in the evidence garage. Ducky arrives with ice cream (starts at 0:33:34 on this episode of the DVD).

Ducky: Ice cream here!
Tony: Thank God! I'm starving! (Gibbs stares at Tony.)
I can wait.
Gibbs: Duck, what are you doing here? It's the middle of the night.
Ducky: How can I be at home in my warm and comfortable bed knowing that my brethren were here toiling away in the name of national security?
Gibbs: Couldn't sleep, huh?
Ducky: Not a wink.
Gibbs: Neighbors again?
Ducky: Or as I like to refer to them: the devil's spawn.

• We find out the terrorist's name in this episode. It's Ari Haswari.
• In this episode, Gibbs has a vision of uncovering Kate's body with a bullet hole in her forehead - this could be a foreshadow of Kate's death exactly a season later because her character dies in the season two finale "Twilight." However, when writing this episode, Sasha Alexander had no intention to leave the show, so this was an accidental foreshadow.
• Ducky has lightning hands. In the lunch scene when Kate gets up he is attacking his salad with knife and fork. When Kate kisses him a split second later, his right hand is already holding his glass to his lips.

• Rudolf Martin is meant to be playing an Israeli/Arab, but:
  1) His accent is distinctly German/Austrian, not Israeli or Arabic Israeli.
  2) Gibbs states he is working in "The Jerusalem Hospital." Jerusalem has four major hospitals. Anyone looking at the information would see the name of the hospital before its location.
  3) The name would be pronounced /Ah-ree/, not /Airy/.
  4) Additionally, it's extremely rare for an Israeli citizen (which he would be, even with an Arab mother - as she would have to be an Israeli Arab and not a Palestinian to work as a nurse in an Israeli hospital) to study in a UK medical school. Tuition is much cheaper in Israel and the level is just as good. Due to the prohibitive costs of overseas training, Israeli medical students only leave the country if they are not accepted at local schools. If he wasn't good enough to be accepted at an Israeli medical school, he would not have been accepted at a prestigious UK medical school either.
• When Ducky and Palmer are piecing together the bodies in autopsy, Ducky pulls out one fragment and says that it's the distal phalange. This is incorrect terminology. Collectively, the bones of the fingers or toes are referred to as the phalanges, but the term phalanx is used to refer to a single bone from the fingers or toes. Distal refers to the location of the bone in the toe or finger-- in this case it's the bone at the tip. In addition, to be specific, Ducky would need to designate which distal phalanx he had identified by using a Roman numeral between I and V, identify it as a phalanx from a finger or a toe, and include which side of the body it was from.
