HISTORY: Project Mercury workers gather 50 years after John Glenn’s orbital trip, visit old launch pad.

Glenn and Scott Carpenter, the only other survivor of NASA’s original Mercury 7 astronauts, spent nearly an hour being photographed with the retirees, posing in front of a black curtain with a model of a Mercury-Atlas rocket. Glenn is 90; Carpenter is 86.

Earlier in the afternoon, the Mercury brigade traveled by bus to Launch Complex 14. That’s the pad from which Glenn rocketed away on Feb. 20, 1962.

Some retirees were in wheelchairs, while others used walkers or canes. Most walked, some more surely than others. But they all beamed with pride as they took pictures of the abandoned pad and of each other, and went into the blockhouse to see the old Mercury photos on display and to reminisce.

Sad that so many of these people have grown old without seeing lunar colonies and Mars missions. That would have been hard to believe back then, when progress was so swift.
