In the case of the SMA the turbo is turning in the ballpark of 16,000 RPM...

I highly doubt that. I haven't seen any of their mapping but generally speaking something that size should be spinning maybe ~7X that fast

You are correct sir, 146,000 RPM is the published limit for the gen 1 engine. So ~9x what I said.

Grob G850 set the altitude record for pistons at 60000ft, so it's not impossible to imagine a scenario where a diesel engine could reach the same altitudes.

I believe the Grob used a piston turbine hybrid engine. The props were also huge making a high wing configuration all but necessary.

No but it sure makes regular ops at FL650 a stretch.

I liked the earlier comment about autonomous freight ops, point to point. Seems like a good mission for this type of airplane.

Take the human out of the equation, and go as high as you want. Being slower than an airliner and taking a hour to climb are less of a problem.

Maybe a human pilot in a pressure suit for proof of concept, then take the human out when the tech and regulators are ready.

I was at KVCV last night.
I asked the ramp guys if they see the OTTO flying much.
They said yes it's been flying regularly.

Which makes Concorde an even more incredible bird/ops.

Surprising that there's no video of it flying yet...

I don't know how much of the "paper airplane" is actually making it into hardware, but they have at least 7 US patents on various concepts..... Generally described in the specification, here:

Still waiting to see a video of this thing in flight.

Does one exist?

New link including flight videos and performance data.

The potential for this air frame is amazing.

A V-12 engine...

It would appear to have a rather long driveshaft.

Those sub $400 DOCs would be awesome. And.... piston single engine ramp fees. Sign me up!
