This is the Pierced Steel Plank (PSP) Caribou ramp on the east side
of Cam Ranh Bay AFB. The interlocking PSP "planks" were used throughout Vietnam
a both a runway surface and a ramp surface. Initially they had a non-skid surface coating
which provided good traction. As they wore, however, they became smooth and when combined
with a little rain and mud, they were as slippery as ice. Visible in the background is a
C-5 departing for the "world". |
