---------------"it got a quarter distance than a fossil fuel drone"--------------------

Here's one that goes 15 hours

MMC UAV Griflion H - Fifteen-hour VTOL Hydrogen Drone. Its flight time reaches a record-breaking 15 hours without payload and it can fly for 10 hours even with a 3kg payload while most drones in the market have a maximum 2-hour flight time. https://www.suasnews.com/2019/09/mmc-uav-griflion-h-fifteen-hour-vtol/

Any more snide remarks?

Is it that you're against hydrogen or just against anything new...

It could fly for months, thanks to its solar powered electric motors.
