I'm sure you'll get an answer to a call on 121.5.
.....by Swanwick Military...... (kind of my point)
Swanwick Military do not close. Ever. Whether they are willing to offer a service is another thing, and prenoting civil traffic that if you fancy flying this weekend expecting a Military service you are not going to get one, then that is just safety in operation. Being told that certain routes are closed due to danger area activity so rerouting is in operation, surely that is standard and just accepted?
I've still got no answers as to how anyone thinks there weren't any fighters in the areas during the closure?.............
