HEAVIER THAN AIR

I live
in Clydebank, directly below the flight path for jets on their final
approach to Glasgow Airport. Every few minutes' huge flying machines
glide past overhead. They bleed speed, slowing to a velocity at which
they can safely land, flaps hanging like great doors. They weigh as
much as five hundred tons; but they fly. Airplanes
are ideas. That's their genesis. Ideas weigh nothing. Da Vinci's sketches
of ornithopters and parachutes never weighed more than the paper they
were drawn on. But ideas implemented, ideas applied, gain weight. They
become heavier than air; but they fly. |
