The morning in question was interesting, I caught sight of the 747 at about 2 miles on final 27R. The aircraft had a significant amount of drift on, as it appeared from my position, perhaps (15-20) degrees.
It was quite early in the morning and the holding point on RW27R ( the departure RW) had several aircraft in situ unable to depart due to SIG WX to the north of the field.
The 744 continued its approach and appeared stable all the way.
The ROD was checked and the drift kicked off beautifully, but the mains went on fairly solidly followed almost immediately by the nose.
To my horror I caught sight of the no 1 pod make contact with the ground. The aircraft continued along the runway and vacated out of my view. A couple of a/c reported the incident over the R/T.
I have been to LHR on more than one occasion.
On the day in question (Thur Nov 3). The turbulence on approach gave rise to conditions that the typical short haul operator might encounter on only a couple of occasions a year.
Tower reported wind and GPS wind just 100' above the RW were significantly different.
On a later approach to LHR wind display at 200' gave the wind as 200/36 when the tower was reporting 210/19.
Have no doubt about the conditions the crew experienced...
From my front row seat the a/c was stable throughout the approach...But hey there but for the grace...go we all.
