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
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.  -- Jim Colligan
