Drone down. An IAI Heron unmanned aerial vehicle of the Indian Air Force crashed today near Bhuj in western India. Indications are that the crash followed engine trouble and subsequent loss of control. The Indian Navy has lost a few Searcher MK.IIs in the past, but I'm pretty sure this is the first crash of the larger Heron, the most advanced unmanned air system currently in Indian service. The IAF and Indian Navy operate about 45 Heron I/IIs between them, with the government clearing a 15 Heron buy 11 months ago.
