I live in the central UK and Military aviation is one of my interests but I cannot say I,ve noticed anything unusual on this side of the Atlantic
other than preparing for the Airshow season.
Last year just before Gulf War 2 got under way USAF Heavy lifters were coming over every 15/20 minutes night and day but at the moment its just
scheduled stuff.
I will let you know if things get busy
You were probaly seeing the C-17 Globemaster III from either Charleston, South Carolina or from McChord Air Force Base, Washington. They are probably
heading to Ramstein Air Force Base, Germany because that is a major stop for the C-17, which is the main heavy lifter in the USAF.
