gantry still standing on the "Cape". The gantry provided access to the
rocket for workers and afforded some protection from the weather. This gantry

gantry is standing at Pad 26B. The gantry is 112 feet tall and could be moved
on rails under its own power. Just before a launch it would be moved back out
of the way. Note the covered room toward the top where the payload would be
mated to the rocket. This gantry supported 36 launches.
Based on the Air Force Space
& Missile Museum virtual tour, it appears that the gantry has been
partially disassembled since my visit in 2005.
