A lot of planes in a small space

The DEBKAfile has an article about war games in Nevada:

Southern Nevadans were warned last week that 62 warplanes would take off twice a day from Nellis Air Force Base, home of 414th Combat US Training Squadron northwest of Las Vegas in the latest eleven-day Red Flag exercise. They will see (and hear) Israeli and US Air force fighter-bombers in dogfights and bombing raids. The size of the air base, 111 kilometers long by 190 kilometers broad, enables large groups of aircraft to practice combat missions in wide spaces unavailable to their air crews at home. A large number of Israeli F-16C fighter-bombers from IAF Squadron 110 are taking advantage of the opportunity for mock combat drills in large groups and bombing missions with live ordnance. They flew in directly from their home base in Israel, refueling on the way. US F-16CGs of the Ohio Air National Guard will join Israeli craft in missions for intercepting and downing enemy planes. Also taking part are US E-3 spy planes and US and British K-135 transports.
