The Indian Air Force has been stunned by the March 28 crash of a C-130J, the third aircraft to be delivered in a fleet of six that began arriving in 2011. As investigations begin into what caused the shocking accident that resulted in the deaths of all five men on board, manufacturer Lockheed-Martin and the US Embassy have both offered to assist in the crash probe. Sources tell SP's the US Embassy has offered to bring in crash experts trained on the C-130J to contribute to the effort. As things stand, the IAF has obtained the flight data recorder and cockpit voice recorder and is currently attempting to make sense of what happened to the aircraft in those final moments. The C-130J was on a low-level training sortie from Agra to Gwalior when it crashed across near the Rajasthan-MP border late morning. The crash took place in an open, rocky area on a river bank that was fortunately unpopulated. Prima facie inquiries show the aircraft may have brushed a low hill before catching fire and diving into the ground. The crew on board the plane were all fully trained, and Wing Command Prashant Joshi, the senior most officer on board, was said to supervising a training flight by Squadron Leader K. Mishra, the only trainee pilot on board the ill-fated aircraft. India had requested US help for the investigation.
