YOU GET WHAT YOU PAY FOR.
You get what you pay for and then you check it out but even with careful assessment with every design, you end up relying on an explosive platform to draw out the explosion a reasonable time. There are so many things that can go wrong with a rocket engine, nearly all of them acoustics related any amount of error could creep in.
Not least of the likely failures may have concerned the cryogenic effects on the unique crystal structure that made the design so fantastic all those years ago. Wouldn't it be nice if they could prove the cost to the integrity of the motor was caused by the stupidity of the pleasure boaters causing the scrubbed launch?
If they can prove it, can they sue?
