$10 an hour still seems really good though right? I’m not sure how much Airlines pay currently for fuel though.

Only article I could find was this: flyinginsight.com/…/how-much-does-it-cost-to-fuel…

On average, a 737 or A320 consumes between 2,500 and 3,000 litres of fuel per hour

Take a typical two-hour flight, such as Amsterdam to Barcelona. The total fuel burn would be approximately 5,500 litres. At a reference price of $0.59 per litre, that translates to around $3,200 in fuel costs.

So that’s $10 an hour down from $1600 an hour? Seems decent.

The terminal velocity of a penny is at least 40 km/h. A Porsche would be much higher. Assuming the Porsche fell that slowly and reached terminal velocity instantly, the cliff would have to be 20 km high for the Porsche to fall for 30 minutes. Given Mt. Everest is just under 9 km high, you would need more than 2 Mt. Everests of height for your cliff to make this happen.

Based on all that, the terminal velocity of a Porsche is irrelevant.

If humans can hang glide I don’t see why we couldn’t use those aerodynamic principles to try to glide a car hooked up to glider wings. It’s a real engineering challenge, but I feel like it would be possible to get some distance in a scenario where a car uses its wheels to go fast, drives off a cliff, deploys some kind of glider wings (or drive with the glider wings timed out to where the car gets to the cliff edge right at the point where the wings plus updraft provide enough lift) to get the vehicle to glide a substantial distance.

Seems horribly dangerous but not impossible.

My 1975 was tuned for distance. When I drove it from Key Largo to Seattle, it did 35mpg average over the 3500 miles I drove. That car was lost in an accident, sadly.

25 miles per gallon. 30 minutes would be 12.5 miles on half a gallon.

My current one does about 25-30 mpg. It weighs 1950 pounds. So, yes. It can comfortably do half an hour on one gallon or so and have fuel left to get me to a refill.

They have flat 4 two liter VW engines. Extremely efficient if tuned correctly. One top of that, there is a direct 1 to 1 drop-in electric kit for these. When my current engine dies, I have an electric kit I’ll put into it to make it an 914E.

Heart aerospace’s website indicates the X1 demonstrator has a 140kt “VNE” - never exceed - speed. So it’s probably safe to assume cruise speed would be closer to 100kt, and $5 of electricity used in half an hour might equate to around 50nm straight line distance.

It’s pretty impressive for a plane roughly equivalent in size to a 30-seat turboprop airliner like the EMB 120

Why would you leave behind a perfectly nice airstrip when your goal is testing a new aircraft? One step at a time, Speedy. Aircraft distance depends on altitude and winds. Not the goal of this flight to break this kind of record. Easier things like time come first. Only then can they calculate how far they can go. Aircrafts can’t park on the shoulder like your 2D vehicles do.
