Goofs

The Ultralight that Howard and Phil are flying in, near the end of the movie, is shot up by the police, a hole is clearly seen having been shot out by a shotgun blast from one of the police cars chasing them. In a following shot, as they are heading towards a bridge, you can see the entire Ultralight from about, and there are no holes in either of the wings, appears to have no damage at all. See more
