Travel mysteries

One of the travel mysteries that I have been grappling with pertain to hand-clapping.  Every trans-Atlantic flight I have ever been on, all the Europeans always clap when the flight lands in Europe.  This isn’t just a one or many occurrence, but every single time.  Why?  My guess is that they are thinking “Thank goodness, we didn’t crash!” or maybe “Wow! We didn’t get shot down.”  If I recall correctly, the hand-clapping didn’t take place flying to South America or Africa.

Maybe I should ask my next trip to Europe.
