This how to stand on air.
it is a addition to the floating cheat(steps 2-7 are the original cheat)
1: equip a kamikaze bomb for 300 credits.
2:equip a hydrogen battery for 50 credits
3:equip a large engine deluxe for 700 credits (1,050 credits total)
4:go to training
5: go near the edge, but go back and forth until the battery begins blinking.
6: hold up(make sure to hold up or else you will fall)
7:you will go off the edge but if you hold the up button you will be driving on air!
8: use the kamikaze bomb.
9: it will explode and you will be still, but on air!!!
10: you will only be standing for one second. then you will fall (but it's training, so you will not lose any money!):)
hope this is useful
