JPL and NASA have tested their incredible 2020 Mars mission parachute three times. The video is a joy. Read the rest

I don't know about you, but back when I was working a nine-to-five gig that forced me to wear pants and show up on time, I had days at work where I wanted nothing more than to knock everything off my desk and set the office on fire. I'm betting it's a feeling that former U.S. Army Sergeant John T. Skipper can relate to.

During a training exercise back in 2016, Sgt. Skipper, now a former member of the 173rd Airborne Brigade, decided that he'd totally be into finding out what happens to a Humvee when its parachute straps are tampered with during a tactical airdrop from a C-130 Hercules.

The answer: As this YouTube video captured by spectators on the ground illustrates, nothing good. However, the premise that a vehicle that reaches terminal velocity during a fall will be destroyed on impact with the ground can't be taken as gospel. An experiment has to be repeated, with the same result, for it to become a fact that you can rely on. So, apparently in the name of Science, Skipper cut the straps on not one, but three Humvees during the course of the exercise.

This past week, Sgt. Skipper was court-martialled for his dabblings with gravity. As a result, he was convicted of three counts of destroying military property with a value of more than $500 and providing a false official statement. "More than $500" is an understatement. While you can buy a well-loved Humvee at auction for a few grand, these days, the ones still in service, or bought new, have an estimated worth of starting at around $70,000. Read the rest
