Explination: settings used: A3 air spawn, full down draft wind, fuel burn rate mult set to exactly 10000000000.0 (this screwed it up pretty bad and ended up ADDING fuel
)
loadout: full fuel with DTs
How I did it:
First thing I did was raise gear, then went full throt, then opend e6b, watched until I got to mach .81,
then droped both tanks and turned on wep at the same time, because of the wieght this created a slingshot effect, I was shot strait up in an insain climb (after I lost quite a lot of metal) to well over 100k before I went plumenting down well past the sound barier. You have to get the timing of droping the tanks just right otherwise you just crash in midair.
I also have a film of me doing it but not from that particular pic.
