When I was operating on 216 Sqn Trimotors, I accompanied SATCO and OC 216 doing a runway inspection around 1992/3. The runway was full of cracks even then.
A contributory factor was (particularly) Trimotors arrivals within quite a tight area and with the high tyre pressures and the nature of the Tristar's undercarriage caused quite a lot of damage when compared with other aircraft types.
Reckon it's more of the same, 8 mainwheels at high tyre pressures on Voyager ?
