It's the latest tidbit on India's $12-billion Medium Multirole Combat Aircraft (MMRCA) competition that's doing the rounds (and it was first reported by The Hindu on Tuesday). Four of the contenders that underwent cold-weather evaluation trials at Leh didn't meet performance requirements. OK, major understatement. Four of the contenders bit dust in Leh. Read that again: four aircraft. That's huge. It's still unclear which part of the Leh test the four aircraft types failed at, though it is quite clear that it was either the switch off/on after landing, or the take-off with meaningful combat load at that altitude. The only thing that appears true is that four aircraft failed the trial -- it is totally anyone's guess which these are.
