Continuity mistake: In the secret room below the deli's meat locker, when Mikaela asks Wheelie for help, Wheelie looks at the first photos of the "language of the Primes", and the positions of the photos change in the following overhead shot though nobody has touched them. (01:19:35)
Continuity mistake: In the secret room below the deli's meat locker, when Wheelie explains that the symbols are the "language of the Primes", Sam picks up two photos, but both photos don't just switch hands as stated in another entry, one changes entirely. In the fist shot Sam holds a photo of a jet, but in the close-up he holds a photo of an old plane, then in the following shot it's back to the jet. (01:19:45)
Continuity mistake: In the basement of the deli, Sam holds two photos of Seekers, one in each hand. The image of the car and plane switch hands and back again in different shots. (01:19:55)
Visible crew/equipment: Before going into the Smithsonian Air and Space Museum, when Simmons throws the bottle of pills at Sam and says, "Slip it under your tongue..." the reflection of the moving boom mic is visible in the car window. (01:20:35)
Continuity mistake: Before heading into the Smithsonian Air and Space Museum, when Simmons pulls the taser out of his bag and turns it on he holds it in his right hand, but in Leo's close-up as he starts to freak out, the taser's in Simmons's left hand, then it's back in Simmons's right hand, between shots. (01:20:40)
Continuity mistake: When Leo walks out of the bathroom with his pants down saying, "Ran out of toilet paper, you got any out here?", the security guard behind him is walking towards him, at the right of the airplane. Next shot that security guard behind him is to the left of the airplane. (01:20:55)
Continuity mistake: At the James S. McDonnell Space Hangar, the entire information booth that is directly behind Jetfire (it was seen close-up when Leo walked out of the bathroom with his pants down) has vanished as he exclaims, "Behold the eternal glory of Jetfire!" (01:21:00)
Continuity mistake: In the Smithsonian Air and Space Museum, Simmons grabs a leather flight jacket, puts it on and when he stands perfectly still between two mannequins his fur collar is first flipped up then flat down, between shots. (01:21:15)
Visible crew/equipment: When Leo has the taser in his hand in the museum's bathroom and then uses it on the security guard, the reflection of the cameraman, who is wearing a white shirt, is visible on the stall door. (01:21:20)
Continuity mistake: After Leo uses the taser on the security guard in the bathroom, the guard is sprawled out on the floor with his left arm lying beside him and the TP roll above his arm, but next shot the guard's arm is up parallel to his shoulder, with the TP roll now between his arm and torso. (01:21:30)
Continuity mistake: At the Smithsonian Air and Space Museum, when Mikaela, Sam and Simmons follow Wheelie they reach Jetfire's enclosure with the large information plaque attached to the metal front bar, as Wheelie faces them. Next shot, that whole front horizontal bar is gone along with the information plaque, and Wheelie now faces Jetfire. Then when the Cube shard attaches itself to Jetfire the metal horizontal bar reappears, though the large plaque is still gone, and that bar vanishes once again in the shot from under Jetfire. (01:22:35)
Revealing mistake: At the James S. McDonnell Space Hangar, upon finding Jetfire, Wheelie turns and says, "This guy's a legend," and then later Wheelie turns and says, "I tell you, this guy did not age well." These specific CGI frames of Wheelie are the very same frames, and only the background plates (with and without Jetfire) differ. (01:22:40 - 01:23:40)
Revealing mistake: At the Smithsonian Air and Space Museum, there is a triangular enclosure around Jetfire that amusingly just fades away and vanishes as Jetfire transforms. (01:23:05)
Continuity mistake: As Jetfire transforms, Simmons orders everyone to hide by the Mig, and as they run to it the tall lighting pole is positioned in the open area between Jetfire's enclosure and two red-trimmed glass showcases. But when Jetfire begins to ask, "What sort of hideous mausoleum is this?" that tall pole is now between the two showcases and there are metal posts with red rope suddenly surrounding it. Then when Jetfire breaks out of the hangar, the lighting pole and metal posts have all vanished. (01:23:05)
Continuity mistake: Just after Jetfire's transformation, when he shouts, "Answer me, pawns and knaves!" he pushes the yellow Naval sea-plane (44), which hangs from the ceiling, out of the way. First problem is that we see it breaking apart and hear it crashing, yet we don't see any pieces anywhere in following shots. Second, when Wheelie mentions that Jetfire hasn't aged well, that sea-plane is back up where it was. (01:23:25)
Continuity mistake: After Jetfire's transformation, when he snipes, "You little spinal-cord-based organisms," he knocks the Mercury capsule and it falls. In the shot facing Jetfire, as it rolls toward Sam and the others, Jetfire is no longer standing within his enclosure, he is actually to the left of it. However, in the next shot as the Mercury capsule rolls toward Sam, the teenager is standing directly in front of the enclosure's bars. (01:23:30)
Continuity mistake: When Jetfire tries to leave the James S. McDonnell Space Hangar and says, "I command these doors to open," there is a shot of Sam, Mikaela, Simmons and Leo standing at the tip of what was Jetfire's enclosure bars, looking up, a bit to their right as if Jetfire was directly in front of them. In the next shot Jetfire, who is way down at the end of the hangar, breaks down the door and heads out. Next shot, they're all still looking up in the very same direction, even though they should be looking all the way to their right, straight ahead into the distance. (01:23:40)
Continuity mistake: When Sam and the rest are chasing after Jetfire, explaining that they just want to talk, during their conversation Sam's arms repeatedly go from being raised way up or being down, depending on the camera angle. (01:24:20)
Continuity mistake: At the aircraft 'boneyard', Sam uses a dagger to carve a huge circle of symbols into the ground, and in the first close-up Sam finishes up a specific symbol at the top of the circle, sticks the dagger in the dirt and stands up. In the next overhead wideshot, Sam is not only still kneeling and then stands up again, but he was actually kneeling at a different symbol located at the bottom of the circle. (01:25:50)
Continuity mistake: When Sam has carved the circle of symbols into the ground, the aircraft behind him casts very different shadows upon the ground right up until everyone vanishes, when the cloud of dust caused by their disappearance appears. (01:25:55)
Answer: After the tomb, he doesn't appear onscreen again. There's no indication as to what happened to him.
