One thing I was wondering of was the kiddie pool under the rocket, I saw it filled and the blob of plastic which was left. Finally I got an explanation of the pics...........
"This is how Wedge explained it... The trailer-mounter launch rail originally had a 45 degree angled blast deflector on it (to protect the trailer wheels and stuff from getting toasted). However, the 3 P motors igniting simultaneously were producing something like 6000 pounds of thrust, and he was worried about sending the trailer shooting off to the side! So his idea was to remove the blast deflector completely and put 100 gallons of water in a kiddie pool under the nozzles. Sort of like the Saturn V/Shuttle water deluge system, I guess. Anyway, apart from vaporizing the kiddie pool, it worked like a charm. The trailer was unscathed (from *that* flight anyway!) and as a bonus, it produced a pretty spectacular liftoff cloud." --Greg L.
Thanks to Greg for the explanation.
