In a message of the 24-May-95 to Glen Collins, you typed:
 
RB>GC>BTW What does BFN mean?
RB>GC>Seeya!
RB>
RB>FAB, SCOTT, THUNDERBIRDS ARE GO!!!!
RB>
RB>You tell me what FAB means and I'll tell you what BFN means
 
I quote from The Sunday Herald-Sun TVextra of the 14-Aug-94, p11:
  "...and tell me 'FAB' stands for 'fully acknowledged broadcast'.  Geoff
  Brown even wrote to the show's creator Gerry Anderson, care of his magazine
  Fanderson (PO Box 93, Wakefield, W. Yorkshire, WF1, 1XJ, England) to get
  the answer."
and The Sunday Herald-Sun TVextra of the 08-Jan-95, p10:
  "This perfectly acceptable answer was hit for a six only a few weeks later
  when more readers wrote in with photocopied evidence from interviews with
  Anderson saying it didn't stand for anything, it was just an abbreviation
  of 'fabulous', a very hip word in '60s England."
Try writing to Gerry Anderson, and post the reply (if any) in this echo.
