I didn’t know we had any?

We don’t, but there’s a fly past going on today so could be part of that

The Americans have several, based at Mildenhall

Part of the mi amigo flypast in Sheffield

Usually in pairs around Menwith Hill Harrogate.

There was a fly past over Sheffield earlier,it was on BBC Breakfast all morning.
They filmed the planes that flew over, no doubt it will be on the national news later,have a look if the plane was there.

I live in North Norfolk close to Marham, Mildenhall and Lakenheath bases.

We get a lot of the Osprey coming over from Mildenhall as well their fast jets, they also come over low and make a really distinctive sound, great things

I saw one barreling down the great glen at low altitude on holiday last summer. It was a sight, about midnight, right over loch Ness with just the tips of the props glowing green.

Deffo the Sheffield one, was tracking it and some of the others on https://global.adsbexchange.com/VirtualRadar/desktop.html

I expect it’ll be on the news later, otherwise check out BBC breakfast from around 08:40 on iPlayer.

Epic machines. I have seen them operating from close distance twice – at the NATO Summit in 2014 and at one of Trump’s visit locations last summer. We were about 100m from a take-off point at one stage, and had trouble standing in one spot, such was the force of the down-draft. They need a fire crew present to land on grass in case the turf catches fire…

That was a good turn out for that fly past
