These four B-52s are from the 5th Bomb Wing, Minot AFB in North Dakota and arrived into RAF Fairford in England under the callsign of HATE11 flight.
The jets are:
HATE 11/12/13 refuelled in AR-20 with ABBOT 71 flight on the eastern seaboard of the USA before continuing on to bombing ranges in the UK. ABBOT71 flight was a mix of KC-135s and a KC-46 I believe.
HATE 11/13 went on to conduct bombing practice on Tain range in North West Scotland before splitting into singles for their transition to RTB Fairford. HATE13 landed at 14:05 and HATE11 at 15:15.
HATE12 went to the Holbeach Air Weapons Range to the east of England and conduced bombing practice for around 2 hours. This aircraft recovered to Fairford at 14:57.Source: youtube.com
