Revealing mistake: In the dance sequence, we see Elaine twirling Ted around and throwing him into the crowd. Watch the top-right-corner of your screen, as the stunt-double lands in the audience you can see Robert Hays (Ted Striker) in the top-right-corner waiting to pop out. (00:19:10)

Revealing mistake: When the plane crashes through the glass at the beginning of the movie, you can't see any wings on the plane. (00:04:30)
Suggested correction: Wings don't sprout out of a plane's nose. They would be significantly further back on the fuselage and out of sight.
Except you can see on either side of the nose, there's nothing blocking the view of the wings. There's no way for them to be so far back that you couldn't see them.
Revealing mistake: When Elaine is visiting Ted at the mental hospital and she says Lt. Zipp died this morning, when Ted picks up the water right before he spits, there's the same amount in the glass when he picked it up and set it down. So he didn't drink anything or spit any water. (00:28:50)
