A short proof of concept flight with one hydrogen-powered engine and one soon-to-be-outdated ICE (for flight safety and comparison). The hydrogen-fueled engine was less noisy and produced less vibrations. They've developed a retrofit kit to use with existing planes and fuel-capsules that ship on existing infrastructure. Sounds like the tech was developed in France, but it's being pre-ordered by many companies arpubd the world. I wonder what pressure we can use to for our local airlines to get on the list?

Oh, at first I thought the squirrel got fed up with the turtle and did it intentionally (but also regretfully). Now I see the vertical lines indicating the falling bullet.
