S77-E-5078 (24 May 1996) --- On the Space Shuttle Endeavour's aft flight deck, astronaut Mario Runco, Jr., mission specialist, grabs a hand-held 70mm camera and prepares to take still pictures of an Earth observation target of opportunity. A pair of windows just out of frame above Runco's head provide the crew members with a prime operating perspective of Earth observation targets. A crew mate exposed the image with an Electronic Still Camera (ESC).
