BREAKING NEWS
The flight plan now gone out as G-BOAG (no flight number) to fly amended routing LHR-JFK etd 1516z eta JFK 1905z.
The LHR-MAN delivery changed callsigns half way through the flight at the request of (I think) Captain Bannister. I assume because Speedbird Concorde AC was more personal than Speedbird Concorde 9020C.
