You dont mention if playing stock or with a mod etc
I know GWX has scripted BoB flights, sailings etc and will guess that WAC and NYGN do as well as LSH
There maybe an issue with too much going on for your computer to handle
Being in the channel means you are close to ports and associated shipping so the arrival of an air squadron may just be too much
Pls post list of mods being used, comp specs and any error message that comes up when you CTD
