With regards to the 747 landing pics, I had an email with the same at work, along with this narrative:
"The importance of landing on centreline cannot be underestimated. Who needs a 150' or 200' wide strip? Actual shots are from a fairly impressive landing operation.
One of SAA's first B-747s retiring to Rand Airport, South Africa
(elevation 5568 feet with 4898 long x 50 feet wide runway!). The 747-100 outer-to-outer main gear tire width is 41.33 ft.
Empty aircraft Vref was 115 kts!
Right on the center line. An inch is as good as a mile. Nice work."
