The guys in this story show all but one of the trappings of being eligible for a Darwin Award themselves, with the exception of the fact that none of them get killed by their feat of engineering. In fact, I think in the end that the author is worthy of a Darwin anti-award... bettering the gene-pool by being smart, and by reproducing.
If you'd care to take issue with his narrative, go have a look at the best urban-legend website on the net, the San Fernando Valley Folklore Society's Urban Legends Reference Pages (it's easier to just call it "snopes.com"), and read this for the a solidly researched refutation of the JATO Darwin Award.
You be the judge. I'll be the itinerant cartoonist.
