Flight over earthquake damaged areas
The reconnaissance flight took place on February 12, 2001. The flight crew was made of J. P. Bardet, J. P. Singh, Colonel H. Singh, and Capt. Rajiv Nanavaty, a pilot from Ahmedabad Aviation & Aeronautics Limited. The flight was rendered more complicated than usual due to strict restrictions on flight zones close to the India-Pakistan border. At this time, no survey flights were allowed by local air traffic control, and only point-to-point direct flights were permitted. In spite of these complications, a flight path was selected carefully to go over the critical areas that had been previously identified thanks to valuable information from the EERI team lead by W. Lettis and S. Jain.
Figure 1 shows the fixed wing aircraft used in the reconnaissance, and the aerial survey reconnaissance team. Figure 2 shows the flight path. The flight initiated in the morning at 7:00 AM and ended at 7:00 PM. Two stops in Rajkot were required to fill up the airplane tanks. For refueling the aircraft, gasoline had to be carried to Rajkot by ground transportation (Figure 4). The flight altitude was set to a minimum of 3000 feet by air traffic control. In some instances however, the pilot was able to go lower to allow closer photographs. Figure 3 shows the portable GPS unit used to track the aircraft position, and to determine automatically the position of digital pictures. The GPS unit gave the location of the photographs after setting a common time for the DVD camera, still digital camera, and the GPS unit.
