I flew at about 1200m/s, about Mach 3 vertical down and the ship exploded.
thanks for the testflight, Axel!
I checked it (never tried that kind of reentry before) in slow motion. When crashing into the atmosphere like this first (at ~13 G or ~130 kPa dynamic pressure) your wings rip off, resulting in the craft falling like a stone. Very shortly after this the craft explodes either due to excessive heat or/and dynamic pressure.
I tried a bit and found a "rescue procedure":
-at 60.000 m face down, AOA ~10°
-open hoverdoors, fire full hovers, deploy airbrake, trim full up, fire full retros
-when atmospheric influences start impacting (at ~30.000 m) close
hoverdoors and retract airbrake. Still fire full retros.
-Now !gently! pull up, continuously checking the
G-meter (dont' pull over 10 G!), until vertical speed is under control.
-Land and relax.
I admit it took me some trials and 8 out of 10 times I exploded. The timing is crucial, because when the hoverdoors are damaged they are blocked and leave a vulnerable opening in the hull.
If you wish I can make a patch that makes the bird even tougher or try to make an external configuration file to enable custom settings for some values.
Greetings!
