[R-390] Kahn SSB Converter

Barry, A correction All BA flights are called Speedbird. The Concorde 
flights were just by their odd numbers West bound and even East bound.
I reported the Kuwait FIR out of FL 290 for 330 and Speedbird chimes in 
out of 690 for 720. These guys flew a parabola with limited level flight
IIRC a BA Capt told me in a flight from London to JFK they would be 
level for maybe 20 to 30 minutes for the flight. Once in a awhile over 
the Atlantic when they answered their SEL CAL they would answer with 
Speedy bird here. They also only signed Speeedbird heavy in terminal 
area and climbing through normal FL's
