tall, thin, irritable
eeeeeew......I have a friend in south London, who lives just under a flight path of passenger planes that land at Heathrow airport.
He told me that large rivets and bolt regularly fall onto his house and garden. I heard that same thing from many other people living in that area.
Blue ice, in the context of aviation, is frozen sewage material that has leaked mid-flight from commercial aircraft lavatory waste systems. It is a mixture of human biowaste and liquid disinfectant that freezes at high altitude. The name comes from the blue color of the disinfectant. Airlines are not allowed to dump their waste tanks mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a plane's septic tank.
