31,000 truckloads of sand

Army engineers say 31,000 truckloads of sand and gravel fed nine concrete-mixing plants on [US air base] Balad, as contractors laid a $16 million ramp to park the Air Force's huge C-5 cargo planes; an $18 million ramp for workhorse C-130 transports; and the vast, $28 million main helicopter ramp, the length of 13 football fields, filled with attack, transport and reconnaissance helicopters.
The chief Air Force engineer here, Lt. Col. Scott Hoover, is also overseeing two crucial projects to add to Balad's longevity: equipping the two runways with new permanent lighting and replacing a weak 3,500-foot section of one runway.
Once that's fixed, "We're good for as long as we need to run it," Hoover said. Ten years? he was asked. "I'd say so."
