Perhaps the ABZ guys can confirm,what has been the largest a/c to land (rather than touch & go!) at ABZ ?
Is it a toss up between the BA 772 or the Sultan of Brunei's A340?
Yes, it is a toss up between the B772 and the A340 for the largest aircraft to land at ISZ.
However the Alitalia B742 wasn't the largest aircraft to fly the ILS at Dyce; it was a C5A Galaxy which shot two approaches on 14/9/1988.
Other interesting aircraft to fly approaches include an Australian airforce B707 in 1990, a Caledonian DC10 in 1993, a Concorde (touch and go) in 1983?, 2 x B52s on 13/3/1992 followed by 3 x B52s in line astern the next day. Talking of formations, some particularly impressive ones to buzz the Unit include 5 x Shacks on 10/3/1989, 6 x Buccs on 12/12/1990 and 4 x Nims on 1/4/1993.
Unfortunately nothing much of note in recent years though, apart from a Kiwi P3 and a RAF C17.
And no, URNumberOne, I haven't turned into a Super Spotter - I just had a look at the "Beat up Book"!
