I decided to experiment and try to create zone, which icreases mass of the ship dramatically (from 1 to 200). Thus, skilled pilot will have to aim precisely, because after he enters this zone his thrust would no longer hold him in the air and he will (probably not) land by the forces of inertia and gravity.
My first try:
Notice how mass changes in inspector.
My second try:
And fruitless again! I can not beat my own game
