Many years ago, when in Russia, I sooned learned why airline passengers carried newspapers on flights. It wasn’t reading material but for up chuck. The airlines didn’t provide barf bags in those days and it was guaranteed someone was going to spew. The pilots had to have all been drunk - straight up, straight down, 90 degree turns, and oh, a squirrel! The passenger planes were nothing but WWII planes and not a single bolt, screw or rivet had been replaced or tightened since then.
