Hydrogen rules the universe Hydrogen powers all spacecraft Hydrogen makes only water 💦

Everyone survive the Hindenburg

Look it up and look at the video

It helps if you don’t coat the envelope or skin of the dirigible with a flammable cousin of thermite. Much of that fire on the skin is the skin itself going up.

[Spktyr]

Because somehow aircraft fuel that’s vaporized is not flammable?

There’s no smoking signs around every fuel point at my local airport. Same thing around hangars.

Challenger failed because the idiot NASA management launched when the engineers told them that the O-Rings were not rated for the temperature on launch day. Blaming it on the O-rings is like blaming your car’s manufacturer for your car breaking down when you put water in the tank instead of fuel.

After researching the hazards of liquid hydrogen, I stand corrected. It's not as hazardous as I first assumed, at least outside of an enclosed environment.

Below is a short video from a AF contracted study from the 60's.

Indeed!

A Jetsons image comes to mind ;-)

Toyota sells Mirai

Would you let your kids drive around in it?

[DakotaGator]

Quite right.

Texan friend insists your Aggie passage is a true story ;-)

Well known before launch. I know from Bechtal engineers involved in the testing of the solid fuel booster rockets.

As the age of robots approaches, cartoons seem especially predictive, with jokesters revealed as the unacknowledged legislators of mankind.

In caricature veritas ;-)
