    I did my best to find any technical data about the flight. Couldn’t find any actual numbers. FWIW it’s not intended to be a standalone method of powering the aircraft for commercial use; they plan on making it a hybrid, which makes far more sense as far as range and payload are concerned. Best guess a 25000 lb aircraft like this will probably cruise around 120-150Kt at a nice, slow, efficient airspeed for a test like this. So maybe a 40-50 mile flight because “air time” probably started as soon as they lifted off.

      Yeah the problem is they also don’t tell us the load during the flight. From the lift equation (let’s be hand wavey) if they’re a similar size to a regional jet (same planform area) your heavy lift is better driven by speed than lifting coefficient. Of course, it’s hard to go fast with electric props, so I wonder if a safe ceiling is probably 400Kt 300Kt?

      Gives a nice range of you know… 40 to 200 150 miles.

      Edit:

      No way. The speed record for a prop aircraft currently stands at about 300Kt. If we use that generously our new ceiling is lower.
