Anyway I am sure you get my drift. That notam took me 37 seconds to read, and decide there is nothing of relevance except avoiding Tibenham by a few miles at least (better still fly high; extremely few microlight pilots fly above 2000ft).
But gliders frequently go significantly higher, and Tibenham is home to the Norfolk gliding club. If there's a competition on, then there will be a lot of plastic in the sky, up to cloudbase and within clouds that are sucking.
