Another killer plane from KSP. · 6:19am Jun 16th, 2020
This one needs a little more explanation.
I'm not sure this one even flies much short of supersonic. I do know that at 300 m/s or higher the thing is nearly unsteerable- probably due to the canards I put on the nose to move the center of lift forward a bit. I'm pretty sure those were a bad idea, at least without control surfaces.
But that's not what killed a kerbal.
