A VC10 did visit BEB, it was not RAF (though one might have) but owned by if I recall correctly the Sultan of Oman, it was to visit the rocket range. BEA"s handling unit had to be beefed up to handle the flight, with a ground power unit being sent over and some extra staff. BEA at BEB had only 3 staff. A BEA Trident 2 also visited BEB once substituting for a Viscount service routing GLA-Stornoway-BEB-GLA.
