It would have to be *very* cold weather for hydrogen to be standing up in it!

The fire on the Hindenburg was caused by the skin of the hull having been treated with dope that was enormously combustible <cue: joke about cannabis>. The R101 crashed because its hull skin tore in a storm. This exposed some of the gas bags, which ruptured, causing the ship to be unable to keep aloft. It caught fire when it hit the ground because safety flares on board ignited when they came into contact with water. In neither case was hydrogen the crucial factor.

Trouble is, wood is a rather low-density store of energy.
