It was a mission deemed impossible. But four days after a Saudia Airlines Boeing-747 aircraft landed at the Tambaram Indian Air Force (IAF) runway instead of Chennai International airport by 'mistake' -after hours of deliberations-it managed to fly out off the tiny airbase. Saudia imported its senior-most, Boeing-trained commander, Captain Jam Joom, for the operation. At 4.48 pm. He performed a near miracle when he steered the huge plane off the tarmac after running the shortest distance for a Boeing-3,960 feet. The airstrip is barely 4,500 feet long and a jumbo requires 8,000 ft strip space for takeoff.
