ok. needs extreme patience, but i reached now a height of 600m without atmospheric shielding, set speed is 103km/h actual speed somwhat around 17km/h

, ships nose is straight vertical.
try to climb further, hull temperature is dangerous but within parameters.
--
i reached 1200m, hull temperature is sinking down, i can accel. some more.
--
2000m, i'm cold as ice (or cool, ain't i?)
--
altitude 3000m set speed 140 km/h
--
altitude 4000m, i'm still alive and as higher i climb as faster i can go, i preassume.
--
altitude 6000m, set speed 210 km/h, slight raise of temperature again
but i think i managed it.
--
10000m, i'm soon over the hill, temperature is slightly raising, lowered speed to set 198km/h
--
try to use time accel now, temp get's lower with each meter
--
30000m i guess i made it
--
40000m speed 1000km/h, all systems clear
--
> 50000m, full speed ahead
no, i can't say that this is true, you won't explode allways (i would have bid my right arm).
