Any shorter than that?
It depends what you consider to be a "runway".
I have a friend (who is based phenominally close to your 335 metre motorway) who is perfectly happy to "put it in" on less than 50% of that as long as conditions permit.
Farmer's fields, beaches, roads and even the odd stately home's gardens are fodder for him to "alight". We're not talking about a microlight either.
It comes down to four things in my opinion.
1 - Pilot capability
2 - Aircraft stall speed
3 - Wind component
4 - Incline
The best Supercub pilot's landing/takeoff run without 3 and 4 above will be outperformed by the best Warrior pilot with favourable No. 3 and 4 above.
Ultimately, a good pilot with the right aircraft and the right conditions can put it down in an incredibly short distance. To give an example I went for a jolly today to WW and was off my strip in under 150 yds and on my return I was stopped within 80% of that. I am not saying that I am a good pilot, just that Points 2,3 and 4 above were favourable.
Now here's some strip flying where factors 1,2,3 and 4 are all there!!!
