Almost right. They flew to Hens and Chickens just north of Bmini, then North. The final radio fix that the Navy had was about 70 miles off of Daytona (thus the Martin Mariner out of Canaveral few north east before it blew up).
There were two major issues.
1: The radio stations from Havana were broadcasting over the same frequencies that the planes were using and Taylor wouldn’t change frequencies.
2: Taylor was not a great navigator. While serving in the Pacific, he made the same mistake, again blaming it on the compasses. It’s just this time he took a whole flight down with him.
There was a biography of him written back in the 80s by Larry Kusche. He is the first writer to actually look at Taylor’s military records.
A late friend of mine, a retired USAF Col and Master Navigator (began on B-47s), researched Flight 19 and did several navigation plots. He concluded that with the probable failure of several compasses or willful ignoring of them because the lead pilot decided not to trust his, that the lead pilot took the flight off to the north or northeast, similar to the posted graphic.
