Classic. No question what the "something" was, since it has been happening since the beginning of multi-engine engine-out training. Get below Vmc and the airplane rolls over--it in fact doesn't actually stall, or spin--and impacts nose down. My 40-years-ago multi-engine training in Twin Comanches and Apaches was probably some of the most dangerous flying I've ever done, though I didn't know it at the time.
Indeed. The CAB report blamed the accident on failing to maintain sufficient airspeed to avert a stall and spin, and then having insufficient altitude to effect a recovery. The plane was at 2500 feet over terrain that was 500 feet, and a DC-3 purportedly needs 3,000 feet to recover from an inadvertent spin (at least according to the CAB in their report).
If you look at the level of experience of the three crewmembers, the accident should not have happened. Podgurski had 6,248 flying hours, including 3,138 in type. Thomas had 5,226 flying ours with 2,801 in type and the instructor, Burke, had 4,342 flying hours with 961 in type. By any accounts, these were experienced pilots. Whether it was a lapse in judgment, concentration or perhaps a distraction, we'll never know. It is not known who was actually at the controls at the time, either. The nose down impact so destroyed the cockpit area that it took over two hours to recover the first two bodies, and only by further demolishing the airframe. The third body was recovered later in the day. They were identified by the papers they were carrying on them.
