There can be no disputing that, over the past few years, the RAF has launched many a fighter towards a civilian airliner that has cast doubt. Equally, it is fair to presume that any such launch starts to turn the decision making cogs such that, on occasion, the PM or a nominated deputy gets a phone call.
Speculating beyond that is rather pointless as I would offer that any FOI request would be quickly rebuffed by an OSA response.
