When a plane did not need to be refueled, it was able to spend less than five minutes on the ground.

British and French planes need to be flown to the region.

A plane needed two independent coordinate sets, a solid took three.

The new plane would need to use the same engine as the DH-4.

In all, the plane needed about 50 changes, plus extensive routine maintenance.

The planes need not carry a maintenance log on board.

Larger planes are heavier, and need more room to stop.

Other planes, however, need new engines to meet the standard.

My plane, however, did not need four months in a sanitarium.

As usual, the light plane needed only a handful of ground on which to take off.
