All I have to say about “blue ice” is that if enough is going mechanically wrong on a plane for some to fall, the airline is actually going to have more worries than the off chance that the blue ice kills someone or causes significant property damage.
Methane and fire do not mix. Even if you do not get the Bourne explosion, the combo melts your house. MELTS YOUR HOUSE. The methane made everything flammable. The flowers didn’t so much turn to ash as melt. It looked like a scene out of Backdraft. Definitely DO NOT try this at home.
