Remember last week the CTV reporter was talking about how Anna and Stern went to the wrong airport the day they traveled and she was sick, and they had to turn around, he thought it was strange. I wish I had a transcript of that report, altho someone else here also heard it.
I didn't see it, but I remember a poster asking why they flew into MIA instead of FTL (or whatever the Ft Lauderdale call letters are).
Don't know about the customs, but slide #21 of Background Information presentation says:
Flew from Bahamas to Ft. Lauderdale with Howard K. Stern and Dr. Eroshevich (psychiatrist and friend).
Due to pilot's error, plane landed in Miami at 5:30PM.
I doubt anyone checked it out...
