S88-52476 (8 Nov 1988) --- John E. Blaha, STS-29 pilot, gets in some training on the operation of one of the payloads for his upcoming spaceflight aboard Discovery. The payload is an Imax motion-picture camera, hardware of which is out of frame here. Blaha uses a light meter to get a reading before
operating the camera in a practice run. The crew met with Imax personnel on the JSC grounds to practice using the motion-picture camera, making its first post-Challenger trip into space. Phyllis Wilson with Imax is at far right. The payload flew on a number of earlier STS flights.
