The wording of the patent was:

	"We claim:
	 The ornamental design for an airplane, as shown and described."

The patent has drawings of the now-familiar shape, although with a much
smaller and hump with an obvious crease between the cockpit and the rest
of the fuselage, looking more of an afterthought than on the real thing.

The date was 29 Oct 1968, valid for 14 years.

On the subject of patents, does anyone know why Boeing did not patent the
use of engine nacelles on pylons to get the engine airflow away from the
airflow over the wing?
