Biggles (1986)

Unassuming catering salesman Jim Ferguson is pulled out of his ordinary 1980s life when he falls through a time hole and lands in 1917. There, he saves the life of James “Biggles” Bigglesworth, a dashing Royal Flying Corps pilot whose photo reconnaissance mission has been shot down. Before Jim can make sense of what has happened, he is suddenly zapped back to his own time.
