The USAF and USN were mandated by Obama-Biden-Harris (and left-over Bush appointees) to burn a large percent of its jet fuel from “sustainable resources” - at three times the cost per gallon of conventional purified jet fuels!
Yes. It is all stupid and pandering to a know nothing crowd.
I remember when Continental Airlines introduced their EcoJet. It was a normal B737. It flew one flight with biodiesel jet fuel in one center tank. At one point in the test flight, one engine was switched to the biodiesel tank for a few seconds, then back to the normal jet fuel tank.
After landing, the biodiesel tank was emptied and flushed. Then the jet was sent to the paint shop where the winglets were painted green and EcoJet was painted on the nose. Tada!!! The climate friendly EcoJet was born for all of the hummus and soy pansies to worship.
It was marketing genius.
