It never turns out good.  One of the most famous airports in the world, Princess Juliana International Airport, sits just feet away from Maho Beach (on the Dutch side of the Caribbean island of Saint Martin), where people swim, tan, and hold on for dear life from jet wash. Jet wash is the force from a jet engine blowing across the beach. Some stand way back and watch, others stand up close and grip the fence. In a new video we learn it's probably better to stand back and watch.
