The practice of 'Due Regard' is still alive and well and wreaks havoc, especially the MN (P3) traffic right in the middle of your holds and busy arrival rush!!
The Global Hawk is pretty much a regular now and we just have to remain 10,000' below once we have determined it is him. We can get comms with 'the pilot' if we need to but mostly liaise through the military.
Things I must say have improved compared to the early days of the ' war's ' as most of the squadron components have deployed numerous times now over the years. The carrier ops are still a shambles but I don't think that will ever change.
