Finmere has gone thru changes since the bad reviews on this site. I have spent 5 months here and during that time 2 gliders have diverted and had their tow planes arrive and aerotow out. Both cases took over 4 hours to complete. No landing fee was charged. No one should hesitate to divert and land if the situation calls for it. That is a called a precautionary landing. Pre planned landings do require PPR, just like most other aerodromes in this country, and will pay a landing fee.

I am a Canadian and not used to this PPR aspect . We are very lucky in Canada to not have that issue.
