I haven't seen too many 747s doing 2 -mile finals and if we put one of the old BOAC brigade in a VC10 on at less than 10 miles fuses would have blown!!!
Neither have I but just because a 747 may find this a bit tight doesn't mean that everybody else that everybody else should have to fly with the same constraints. As for the old buffers in the VC10, they'd spit the dummy if the wrong cheese was on the keyboard. One wonders if these people actually enjoyed their jobs unlike the some of Trident crews who appeared to relish a challenge.
And finally Adam, don't confuse IFR with IMC. The former is a set of rules regarding tracks, levels to be flown, instruments to be carried etc. and the latter describes conditions when conditions (flight visibility, distance from cloud etc.) described under VFR can not be met.
