Goodness me guys. Some of us here are supposed to be highly qualified professionals.
A leak would likely release far less radiation into the atmosphere than is released from coal-fired power stations today.
Radioactive coal? Coal power stations are radiation free.
there have been loads of experiments of crashing Phantom fighter jets, speeding trains etc into nuclear caskets with no resulting breach of integrity.
These were flasks used for carrying nuclear waste from the power station to the storage / reprocessing plant. They were not reactors. A fully functioning nuclear reactor is a whole different kettle of fish and is VERY vunerable. A leak/crash would be catastrophic. Chernobyl.
You will never fly a nuclear powered aircraft. It's scary to think that some of these comments could be from airline pilots!
