Use the patented NinjaBill landing technique...
Just fly at the gound til you feel scared, then pull back til youre not scared, and the plane will touch down.
If you pull back to early, you know not to be so scared next time, so wait a bit longer.
If you build up too much bottle, and round out to late, then the landing will be on the firm side, and you know to be a bit more scared next time.
