Mr. Chair, obviously I can't speculate on why it missed. There could be a multitude of reasons that I'm not privy to, based on what the pilot was seeing in the cockpit, the type of missile shot that he was taking and the quality of that missile shot.
That being said, missiles don't always hit their targets. That's why you always take a shot; you analyze, and then you take a shot again. However, clearly we're seeing that the infrared missiles that are being used have a high probability of success against these targets.
