Project FIRE
The Apollo Program's Project FIRE (Flight Investigation Reentry Environment)
studied the effects of reentry heating on spacecraft materials. It involved
both wind tunnel and flight tests, although the majority were tests with
Atlas rockets and recoverable reentry packages. These flight tests took
place at Cape Canaveral in Florida. Wind tunnel tests, however, were made
in several Langley tunnels including the Unitary Plan Wind Tunnel, the
8-foot High-Temperature Tunnel and the 9x6-Foot Thermal Structures Tunnel.
