Jets are less efficient because they're designed to carry large amounts of cargo and/or passengers. This plane was at near max weight, 25,000 pounds, with zero cargo or passengers

The entire thing had to be stripped down. Single pilot op because they didn't have the capacity for a 2nd seat and pilot

All this "jet" can do is transport its own batteries short distances, slower than a Cessna 150, and very low altitudes

27 minutes of slow flight in a 150 at high density altitude, well leaned out, would cost about the same and have the ability to carry a passenger

This plane is nothing more than a marketing ploy. At least it's quite effective at that
