They call them land sharks. And they keep you alert all weekend.


Here's a P motor CATO from earlier. They are also affectionately called an Rapid Unscheduled Disassembly.

    Took me awhile to figure out what the heck it was. It does make a pretty spiral though.

    Nice euphemism. Kind of like "Controlled flight into terrain" -- FAA-speak for slamming into a mountain.

    "Unscheduled Rapid Disassembly" - ha ha :) a bit like Pan Am's classic "negative profit" expression!

    i love politely optimistic circumlocutory acronyms like this... most policemen / women in the UK speak like this at all times ;)

    now is the time i quit moaning about when the catherine wheel fell of the clothes pole in the garden...

    I just posted a video of a supersonic shred on Revver. The rocket screamed to Mach 2 on a L-size motor, and the pressure wave ripped the fins off making it temporarily unstable (corkscrew). You can hear the warning siren (something I was used to hearing by that point… =) and the chatter of people spotting the fins and other chunks as they rained down around us. A classic Rapid Unscheduled Disassembly.
