Plot hole: At the start when the guys are infiltrating that building they parachute down to the roof. They are dressed in black so they can't be seen, but their parachutes are white. (00:02:50)
Plot hole: After the President sabotages the fuel pumps, two of the bad guys go down and manage to repair the damage. They then proceed to go back upstairs and (supposedly) lock the President downstairs... Where he would be free to simply sabotage the fuel pumps again.
Suggested correction: Harrison Ford tricks the other Russian watching the conference room door and holds him at gun point to escape the cargo hold, you can't miss it.
The point by the poster is that the guys who fixed the sabotage didn't know the president had escaped, so they thought they were locking him in the lower compartment where he could then just sabotage the plane again.
