In 1954 after a research flight in the Boeing B-47A Stratojet Crew Chief Wilbur McClenaghan (center) asks of the pilots if there are any ''squawks'' that should be taken care of before the next flight. Pilots are Joe Walker on the viewer's left and Stanley Butchart on the right. Data system technician Merle Curtis, in coveralls, is busy checking the airdata head mounted on the nose boom with the help of Instrumentation Crew Chief Raymond Langley. The door to the cockpit area is open showing a view of the ladder that folds down to be used by the pilots to enter and leave the area.
