Tom Cruise Actually Clung to the Outside of an Airplane for the New "Mission: Impossible" Movie

TOM CRUISE has been doing his own stunts for years . . . but he may have performed his most dangerous stunt yet for"Mission:  Impossible - Rogue Nation".There's a scene where Tom clings to the outside of an airplane as it takes flight . . . and yes, he REALLY DID IT.  He was strapped to the plane, of course.  But it's still pretty insane.  And they had to do EIGHT TAKES.
