Is the new CAE centre on Fleming Way, next the the Virgin base? There is a press release from autumn last year and YouTube video saying that they will move sims from the “old” Gatwick centre which will then close(?).
Is the “old” centre the one at Burgess Hill? I had always thought Burgess Hill was a district of Gatwick/Crawley but a look on Google maps shows it is around halfway between LGW and Brighton. Or was there already one located in Gatwick?
