Returned to "Stock" KSP after RSS and decided to make some physics witchcrafts.

Could go much faster but the limiting factor was linkage between engine and fairing (even with autostrut).

2nd limiting factor is that after reaching insane speed the colision with terrain is random. Sometimes i managed to phase through entire island.

On the ship there were 2 kerbals just in case one would have an accident.

What a wonderful game.

Stock KSP 1.12.3

Used glitches and exploits:

• KAL overclocking
• KAL reverse thrust for fuel
• Recursive occlusion using fairing and -[Top Secret]- (credits for Strantzeblitz75)
• Collision physics freeze aka Kraken Lithostaging
• Part Clipping
• KAL for automation and perfect timings

For moderators: I've also recorded a tedious 5 hours video of failed attempts including building and editing process if necessary. Aero debug confirms that config files are correct. The craft itself just has absolute 0 drag and goes insanely fast.
