The Comp Cell come to ASCOT Ops with the problem if there are no quick and obvious civvy outlets to shift their passenger(s). ASCOT then look at potential airborne assets, and/or ask Northolt for availability, whereupon if there is nothing worthwhile already operating ASCOT will generate a task.
Normally this will be a C130, but as ever it's subject to what's available and normally involves a degree of horsetrading.
But it's actually a doddle managing a heavily tasked, ancient fleet and, as you can see from earlier posts, provided we cock everyone around, we're happy.
