The width of the runway at RAF Negombo (Katunayake) in Sri Lanka was I was told when I was stationed there in the late 1950's the widest in the RAF, can't remember the exact width but 75 or even 100-yards rings bells.
I went back there in the early 1980's but don't remember whether the runway was still as wide as is was in the 1950 - 1960's.
Photos from my album:
Finals to runway 22.
RAF Negombo (Katunayke) runway 04 as it was in 1958.
And yes V-bombers did use Kat's runway as this view of two Valiants, a Comet, Hastings, Valleta, Shack, Connie and something else in the background (Twin Pin?) shows.
