A small plane attempting an emergency landing crashed into the frigid Hudson River, but the pilot and a passenger escaped the wreckage and safely swam to shore. The Federal Aviation Administration says the crash occurred Monday night, shortly after the single-engine Cessna 172 took off from Long Island MacArthur Airport in Ronkonkoma. Emergency responders were dispatched to the reported crash site but initially could not locate the aircraft. The plane was spotted a few minutes later in waters off Newburgh, about 62 miles north of New York City. The pilot and a passenger were being treated at a hospital for undisclosed minor injuries.
