[QUOTE=Syndrome;4975481]Hydrogen? No thanks.

the 'explosion and fire' was aluminium oxide, the silver covering(paint) not the hydrogen.
if you can find it check the colour images, the flames are blue/green, which is aluminium burning, not hydrogen, which burns with a clear flame.
interestingly enough, the aluminium oxide paint, is very similar to the solid fuel used in shuttle launches.
