You're almost out of fuel in New York, and there's only one way to land, get rid of all the empty buildings in the city.

The space bar will release the bombs to destroy the buildings. The program is somewhat lenient with us as it will allow us to take down some buildings without too much trouble, although our landing gear might get damaged.

If we manage to land safely, we will be greeted with an appropriate tune “Those Magnificent Men in their Flying Machines” and we can start a new level where the bombs are smaller.
