I never knew this:
https://en.wikipedia.org/wiki/Allen_Funt
On February 3, 1969, Funt, his wife, and his two youngest children boarded Eastern Airlines Flight 7 in Newark, New Jersey with a destination of Miami, Florida. While en route, two men hijacked the plane and demanded passage to Cuba. However, some of the passengers, having spotted Funt, believed the whole thing to be a Candid Camera stunt. Funt repeatedly attempted to persuade his fellow passengers as to the reality of the hijacking, but to no avail. The plane later landed in Cuba, finally convincing the passengers.
I believe the movie in #42 was “Sack Lunch.”
