That opening shot of the flying boat is real and is the opening sequence from a major movie whose name totally evades me. Possibly Forever Young, or of that ilk, name wise.
If i remember correctly the guy who flys the plabe upside down going under the bridge with hundreds of people lining the banks got a prison stay for that stunt!
I was under the impression that the under bridge flight was at Red Bull Air race in the Netherlands? Didn't hear of any prosecution though you probably get the insider's track on this one.
