Continuity: In the beginning of the scene where the Decepticon is on Air force One they show a 747 but when they land and they show the Decepticon sneaking off the plane the Air Force One shown is a KC-135. Although you don't see the whole plane, the engines are that of a KC-135, long and slender versus big and round like a 747. Also, you can see the refueling boom, which a 747 does not have.

Revealing: When Banachek shows Secretary Keller the photo of Blackout from Qatar, it's taken from the video of the Beagle 2. It's the same transformer in both pictures. Submitted by Brad

Continuity: When we hear Sam's recording on his phone, it sounds nothing like what he actually recorded. Submitted by Brad

Continuity: When Banacheck shows Sen. Kelly comparative photos of Blackout with the one from the beagle probe and Epp's photo, the latter one shows the sun behind Blackout although it was taken at night.

Continuity: When the news crew is interviewing Sam's parents during the credits, the way Ron holds Mojo changes. Submitted by Brad

Revealing: When the Predator arrives at the desert attack, it doesn't cast a shadow on the ground, revealing that it is a CG plane. Submitted by Brad

Revealing: When Bonecrusher throws the car off the car-carrier, you can see that the underside is just a flat black-painted surface with no gas tank. Submitted by Brad

Continuity: When Josh Duhamel's wife is watching the broadcast saying that everyone at Qatar was killed, the door is wide open. When she sits down to feed her baby, the door is now closed and the high chair has been moved accordingly.

Continuity: When Mikela hotwires the tow truck, it has an automatic gearshift. Later, when she is driving and Bumblebee is shooting, look closely, it's now a manual transmission. Submitted by wizard_of_gore

Revealing: When Devastator (the tank-bot) is activated and exits its base through a fence, the upper, obviously-rubber, cannon barrels wiggle around. Submitted by John W Rosa

Factual error: The guys in the pentagon say "Predator's coming up in a minute". Twenty seconds later we see this so-called Predator. It has a jet engine and a regular V tail. An RQ-1 Predator UAV has a four-cylinder engine (propellers) and inverted-V tails - /\. An MQ-9 still has propellers - so no jet engines yet!

Factual error: In the beginning scenes which take place in Qatar, you can see mountains all around in the background. Qatar is surrounded by desert, and has no mountains. Submitted by wizard_of_gore

Continuity: In the scene where Mikaela is telling Sam about her juvie record, he puts his sweater on. When it jumps to the next shot his sweater is on his shoulder. It stays on his shoulder for the next couple of shots, and then it goes back on and stays on.

Continuity: In the scene when Sam is being chased by two dogs and is led into a strange-looking place, when Sam climbs on top of a barrel, notice that the dogs disappear once Bumblebee drives in. Also notice that when Bumblebee drives into that place, he does a 180-degree slide, and in the next shot he's seen circling around Sam.

Revealing: When the bus splits, you can see that it has no seats or passengers. Submitted by Brad

Revealing: When Blackout sees the green laser light on him, he turns around and flips over some cars, a couple of which don't have engines in them.

Continuity: When Mikaela is telling Josh Duhamel that she'll leave as soon as she gets Bumblebee out of the area, watch her hair. At first, her back is to the camera and her hair is perfectly smooth but when the camera is facing her, her hair is extremely messy.

Factual error: In the scene where Defense Secretary Keller is having the press conference at the pentagon after the attack at Qatar he said "bases worldwide are at Defcon Delta our highest readiness level" which is incorrect. DEFCON stands for defense readiness condition and is ranked in numbers from 1-5. Force Protection Condition (FPCON) also know as (THREATCON) is ranked from Alpha to Delta, Delta being the highest level. FPCON measures the defensive state of American bases while DEFCON measures preparations for war.

Factual error: The Secretary of Defense states that the remains of the defeated Decepticons were dropped into the Laurentian Abyss, "the deepest point on Earth". The deepest point on Earth is actually Challenger Deep, in the Mariana Trench. Given the location was specifically chosen BECAUSE it's the deepest point on earth, it would have been properly researched by the characters, making this a movie mistake rather than a character mistake.

Continuity: In the city, after Ironhide flips over the missiles that Devastator shot at him, he can be seen falling very close to the ground, but in the next shot, he is much higher up so that he can then shoot himself back up-right.
