I knew the guy at Sikorsky who did the post-mortum on the helicopter. He said, the sand clogged the engine, the helicopter was not designed for the desert. Sikorsky fixed that problem. Jimmy Carter was blamed not for the failed mission but for being SO weak that the Iranians would even attempt such a coup. They knew the president was impotent. Iran should have been turned into a Walmart parking lot for that little excursion. Amazing how history repeats itself? Weak president = captured Americans or dead Ambassador.
