You can't make an omelette without breaking a few eggs.  ;D



Since you're not going into space, you don't need the liquid oxygen, just the H.  Also, according to that graph, compressed H at 700 bar pressure has similar volume/mass to energy ratio as the liquid version, so you probably can get away with using that and stay away from the liquid.

Now granted one of these thing going boom at JFK would be a pretty big disaster, but not as big as an LNG carrier going boom as it's being filled in Maryland or offloaded in Belgium.  They are pumping millions of gallons of this supercooled liquid fuel every month these days and so far we haven't had a major boom yet.  Liquid H is closer to Absolute Zero, but the cooling, pumping and storage equipment is all the same.

As disasters go also, I'll take a planeload of stockbrokers being incinerated over a nuke meltdown at 3 Mile Island.  I mean really, mainly the dead people would be the passengers, only a few ground crew would likely be inside the blast radius.  If you're worried about being vaporized on takeoff, stick to sailboats.  :)
