Other mistake: In the opening scene is a paragraph describing why the Top Gun school was started. The word "insure" is used when the word should have been "ensure". They wanted to guarantee the U.S. had superior pilots, not take out an insurance policy.
Other mistake: When Chozen is buying vegetables from the villagers, one of the weights from the scale is knocked onto the ground. Daniel picks it up and realises that its not a real weight and breaks it in half. If Chozen wanted to cheat the villagers when he weighed their vegetables, he would need weights that were heavier than normal, not lighter plastic ones. Lighter weights would mean that Chozen would need to add far more of the light weights to make any amount of vegetables balance out, therefore he would be paying more for the vegetables than they are worth.
Other mistake: When Sarah smokes in James' office he tells her that he doesn't like it because of the fire hazard. Therefore, it doesn't fit in the picture that he doesn't react when she puts out her cigarette in the waste paper basket, certainly a serious fire hazard and worth checking even if James' comment had been a joke.

Other mistake: In the scene where Terry is at the computer, and Jim Belushi's character surprises her while pretending to be a Sperry repairman, they keep turning the monitor on and off. But the last time you hear a beep, which is supposed to be Terry turning off the monitor, her hand is nowhere near where the button would be. They obviously added the sound effect later.
Other mistake: In the scene where Howard falls asleep in Beverly's apartment window and his wallet falls out, she takes out the money. The city on the bill says Washington DC instead of Marshington DC. (00:19:00)
Other mistake: As Packard backs out of the cemetery there's no damage to his car, despite crashing through an iron fence and headstones.
Other mistake: After Jack climbs up the ladder and through the floor he then runs right to the locked door, all this takes about ten seconds. Somehow in those few seconds Wang, Gracie, and the rest of the girls have all made it up the same ladder and coming around the corner when he gives him the signal to come to the door when there's no way they couldn't have all done it that quickly.
Other mistake: Maureen cuts her wrists with a razor blade. Days later, no bandages or scars.
Other mistake: When Eugene discovers that it really is Blind Dog Fulton, he (Fulton) says that he needs to get out to help Eugene find that lost song. Eugene says that he will be here at "5:00 a.m." When they breakout - which took all of about maybe 10 minutes, it's very light for the morning time. Looks to be maybe 6:30 by daylight savings time.
Suggested correction: Aside from the fact that daylight continuity is seldom strictly observed in any film, you should be aware that dawn on the East Coast visibly begins breaking over the Atlantic at around 4:30 to 5:00 AM during Daylight Savings Time. The sun may not have cleared the horizon, but the sky is really quite bright in New York City (and the whole East Coast) by 5:00 AM.
The time of sunrise varies and, although it isn't pointed out what month they left the nursing home, it is suggested that it was during the academic year - not a summer month when sunrise would be within the earliest time frame. Astronomical, nautical and civil twilight (all 6° or more below the horizon) do not radiate the amount of light shown in the movie. Moreover, it did not appear to get lighter out as they traveled, suggesting they departed after daylight, which would be well after 5 AM.
Other mistake: When Turnip runs off with a horse suppository up his hindquarters, the policemen shoot at him being all in a straight line with each other - in fact it really looks like they should be shooting at each other if those guns were real. (01:05:55)
