 The movie is in the Guinness Book of World Records for the costliest  aerial stunt ever performed. The scene in which Travers crosses from  one jet to the other at a height of 15,000 feet was done without the  aid of any safety devices or trick photography. The insurance  company underwriting the film refused to insure a stunt man for  this, so Sylvester Stallone (qv) offered to reduce his own fee for  the movie by the amount that the stunt cost to produce in order that  the film could be made. The stunt was performed by  Simon Crane (I) (qv). Because of the extremely dangerous nature of  the stunt, it was only performed once.
