And have you ever wondered what naughty people would do with these dangerous liquids? Why, they'd merely cool them down to minus 20 or so (obviously nothing special required here then...) and then carefully, drop by dop add the fuel to the oxidiser... OOPS!.... Wrong way round!
New team. Add the oxidiser to the fuel and mix it up VERY CAREFULLY. Then, after and hour or so at your seat, totally un-noticed, mixing unstable liquid components (at 20 below zero with all the paraphenalia that that requires) announce to a totally unsuspecting set of cabin cleaners at your destination, that you have a bomb. They hate their job so much that they ask you to detonate it!
Gosh! I wonder who has won!
