In 92 (after I lost my first "last job in aviation") I was ferrying a C172 for a friend of mine from Florida to Dominican Republic when after a fuel stop the oil pressure started dropping..., long story short I wasn't able to reach Miami center (there was a communication blind spot after Staniel Key, or at lest there was back in those days) but I was able to get in touch with a Dominicana airlines FE that was on listening watch in 121.5, they forwarded my location to the coast guard and I was rescued a couple of hours after I had to ditch, so as you can imagine I'm a big advocate for monitoring 121.5.....!
No kidding...How bad was the crash? Was it hard to get the raft out?
Congrats on surviving!
