I'm still leaning toward the explanation's ultimately being some weird concatenation of accidental events--not some sensational conspiracy. But we may never know. 65 years on, we still have no idea what happened to Star Ariel, a case just about as baffling as MH370:

I can recommend two forums following this story which seem to have a better S/N ratio than most (less raving lunacy.) The first is a professional pilots' forum:

The second seems more oriented toward mariners:

Both have lots of posts and a considerable amount of informed speculation.
