One of the aircraft concerned was XL321 AKA "Rusty Bin". This was last used by 50 Sqn and was one of a pair sent to Catterick for the Fire School.
They had to approach over the A1 low, as Catterick does not have a very long runway. The Civvy Police were due to close the A1 to allow the bombers to land, but there was confusion as to the arrival times of the aircraft. The civvy Police used Local, but as per usual, the RAF used Zulu and the aircraft arrived an hour early and gave the commuters on the A1 a very low pass.
I can not remember the other aircraft, but was on the see off team for Rusty Bin.
