Continuity mistake: In the scene where everyone arrives in Egypt, when everyone is standing around Jetfire, there is a wide shot showing everyone and you see Mikaela sitting down wrapping Sam's hand. Then she stands up in that same shot, and it cuts to a close up that shows Mikaela sitting down again wrapping his hand. (01:27:45)
Visible crew/equipment: In Egypt, in the exterior shot just before Sam says, "We got cops!" the moving shadow of the filming vehicle is visible on the ground and on Sam's car, as it's driving alongside. (01:31:50)
Continuity mistake: In Egypt, the protagonists are being chased by the police. At first the cops are driving an Alfa-Romeo 164. A moment later they are driving a Peugeot 405s. (01:32:00)
Revealing mistake: When Sam, Mikaela, Simmons and Leo are being pursued by the police in Egypt, one of the police cars slams into a parked red car. This shot has been flipped. Note that the driver is on the right side, whereas in other shots the drivers are on the left. (01:32:10)
Factual error: When Sam, Mikaela, Simmons and Leo are at the border crossing, the flag that is flying is that of Tajikistan, and they were supposedly transported to Egypt. Tajikistan doesn't border either Egypt or Jordan, the two countries that were mentioned. However, the insignia on the berets the soldiers were wearing match that of the Egyptian flag. (01:33:00)
Continuity mistake: In Egypt, when Sam says, "We got cops!" they're at a fork in the road, and with two police cars heading towards them from the left of the 'fork', Sam drives to the right of the 'fork'. However, in the next shot, the two police cars are driving past Bumblebee and the twins on the very same road, just before the police cars make their U-turns. (01:35:55)
Factual error: In the scene where Galloway parachutes out of a C-17, Major Lennox asks Galloway if he is "familiar with the standard MC-4" parachute as he is helping Galloway don said parachute. The parachute that actually deploys when Galloway pulls the ripcord is not an MC-4, as MC-4 parachutes have rectangular canopies (shown correctly later in the film as the NEST team descends into the desert). (01:38:20 - 01:40:00)
Revealing mistake: After Galloway says: ''You just signed the death warrant on your career major'', we get an exterior shot of the C17 banking sharp to the right, at an angle of nearly 60 degrees. But in the following shot on the inside of the plane, everyone is still standing, and Lennox and Galloway haven't even moved. (01:39:30)
Continuity mistake: When Leo is freaking out in the back seat of the car, Simmons, who is in the front seat, pulls out the taser to use on Leo and holds it in his left hand as he turns around. Yet in Leo's close-up, as he's being zapped, the taser is in Simmons's right hand, but next shot the taser is back in his left hand. (01:46:55)
Continuity mistake: When Devastator is sucking up the vehicles and structures at the construction site, the large camper's exterior is pulled off, leaving only the frame as the camper is pulled forward, but a few shots later, in an overhead wideshot that camper is still intact and straight, as Mudflap and Skids stand firm. (01:56:55)
Continuity mistake: At the start of Bumblebee and Rampage battling it out, Rampage knocks a car over onto its side (perpendicular to the car that's beside Ron and Judy). A few shots after the close-up of Bumblebee dropping his yellow faceplate over his face, that car gets overturned again behind Mikaela, though in between there are shots of the car already on its side. That car is down yet again when Bumblebee is attacked by Ravage, and then on its side again when Sam pulls Mikaela by her hand. (02:00:20)
Continuity mistake: When Bumblebee is battling Rampage, there's a close-up of Bumblebee as he dramatically drops his yellow faceplate over his face. In the next shot, Sam is on the ground in front of the car on its side (Rampage overturned it moments before). Problem is in the next shot Mikaela is also in front of that very same car, but Sam is gone, and she wasn't seen in the previous shot of Sam either. (02:00:30)
Continuity mistake: When Simmons is on the radio with Captain Wilder, who is aboard the USS Stennis, the radio cord around Simmons's neck is either over or under the flight jacket's fur collar, and then in the last shot the cord is suddenly off. (02:05:15)
Continuity mistake: Devastator demolishes a fair chunk of the top of the pyramid. In the shot where it falls down after being destroyed, the top of the pyramid is still intact. (02:11:20)
Continuity mistake: In the scene where Captain Lennox pulls Mikaela from Sam after he has been blown away, you see her lying on the sand with the right side of her bra cup exposed but when you see her again her top is in the right position. (02:12:40)
Continuity mistake: When Lennox is trying to revive Sam, there is a close-up of the sock starting to slip out of Sam's grasp, but it's still in his hand. Then when the medics are using the paddles on Sam, clearly there is nothing in his bandaged hand. The problem is that there is another close-up of Sam's hand, after Mikaela professes her love, and the sock is still there in Sam's hand before it dramatically falls (it's the same close-up angle as the previous shot). (02:13:40)
Continuity mistake: At the end, in the first aerial shot of the aircraft carrier, only a huge number '7' is imprinted on deck, but after the close-up of Mikaela and Leo there is also a huge number '4' imprinted on deck beside the '7', that is seen as Optimus and Sam stand beside one another. (02:21:25)
Continuity mistake: When Mikaela and Leo are in the silver Saturn, as Sam is hanging onto the passenger door, the rearview mirror is broken and hangs from the windshield, but is then intact once again.
Factual error: In the original Transformers, Tyrese Gibson's character is credited as and wears the rank insignia of a USAF Technical Sergeant. In Revenge of the Fallen, set two years later, Gibson's character now wears the insignia of a USAF Chief Master Sergeant, three ranks higher than his rank in the first movie. The USAF would not jump someone three grades into the top 1% of the enlisted force no matter what his heroics or experience (that does not even happen to Medal of Honor awardees). Clearly the screenwriters recognized this as Captain Lennox is bumped only one grade to Major despite his actions in the first film and Gibson's character, as noted in another mistake, is credited as Master Sergeant Epps, a reasonable promotion. The costume department simply got the insignia wrong.
Factual error: The team go to the Smithsonian Air and Space Museum's Stephen F. Udvar-Hazy Center, which is located adjacent to Dulles Airport in Virginia - surrounded by rolling green hills - to find a Transformer. When Jetfire breaks out of the museum, beyond the broken door is a large, desert airplane graveyard with large mountains in the background. This appears to be the 309th Aerospace Maintenance and Regeneration Group (309 AMARG), a well known aircraft 'boneyard', located at Davis-Monthan AFB, in Arizona.
Answer: After the tomb, he doesn't appear onscreen again. There's no indication as to what happened to him.
