On the topic of frozen objects falling out of planes, I recall an incident a few years back with a plane on approach to Glasgow airport over Motherwell ( a nearby town ) which for whatever reason decided to eject the contents of it's liquid waste tank resulting in a massive block of frozen urine nearly landing on a group of people who were in the middle of a funeral procession.
