Biggles(1986)

Fast food executive Jim Ferguson stepped out of his 47th floor office to go to the bathroom... and ended up in the middle of World War I. History will be grateful forever.

Unassuming catering salesmen Jim Ferguson falls through a time hole to 1917 where he saves the life of dashing Royal Flying Corps pilot James "Biggles" Bigglesworth after his photo recon mission is shot down. Before he can work out what has happened, Jim is zapped back to the 1980s......
