We've all been on flight before that have had some turbulence. You might have even had a little bit of a warning from the cockpit about buckling your seat belt and making sure it stays buckled. This is a whole new level that we have never seen before. The turbulence on this flight sends the flight attendant and even the drink cart up to the ceiling of the aircraft and then crashing back down on passengers. Sadly several people were injured in this event, and we can't help but think of any poor soul who might have been in the airplane toilet at the time of this happening! Could you even imagine? There aren't enough vouchers for free flights to make that all better. Remember to ALWAYS keep you seat belt buckled, even if that Captain has turned off the fasten seat belt sign!!
