The X-24A was designed to test the concept of lifting-bodies (aircraft that derived lift from the shape of their fuselages rather than wings) as part of a study into reusable space craft. It flew between 1969 and 1972.

The X-24A was designed and constructed to take part in the United States Air Force experimental program to test lifting bodies.

It was the fourth lifting body design to be tested by the United States Air Force, following on from earlier Northrop aircraft.

The X-24A made its first unpowered flight on 17 April 1969 and its first powered flight on 19 March 1970.

It made 28 flights, always carried aloft by a modified B-52.

At the completion of the test program it was converted into the more stable X-24B.

Two jet powered X-24As were built but not flown.

One ended up in Hollywood where it appeared in a number of science fiction films.

This model represents the only X-24A in 1969.
