I have it on good authority that this happens when they flush the toilet on an aircraft. This is why amateur astronomers always keep their mouths closed when looking up into the night sky.
After Massachusetts elected Paleface Lizzy Warren, I always ask the flight attendant to let me know when we’re over Massachusetts. I usually have some White Castle sliders if I know the flight goes over Massachusetts. Some of the passengers get a little worried when they hear me yelling “Tora! Tora! Tora!” In the airplane restroom.
