They logged 338 hours of operations of the Apollo Telescope Mount, which made extensive observations of the sun's solar processes.

The family-owned corporation provides technical support services in zero-gravity human factors engineering, procedures development, operations analysis, training and systems integration.

[28] Fédération Aéronautique Internationale awarded the Skylab 4 crew the De La Vaulx Medal and Vladimir M. Komarov Diploma for 1974.
