[canberra]

heres a good question whats the widest runway in the uk? i reckon its the one on the beach at southport which is in pooleys , if i remember correctly its over 100metres. i may be wrong though, i have been before!

I believe it was and possibly still is London Manston. Whether that's changed now I don't know.
I believe it's in the region of 250m. Anyone confirm this?
