The problem with 24hrs notice is the usual vagaries of aviation! I think its about time this situation was reviewed by the authorities, whats the general opinions of the people here? As i said before, you can just get in your Fairline, Sunseeker or whatever and go pretty much anywhere you like. The white flag was dispensed with years ago. Everyone knows 99.9% of prevention of organised crime, bombs, drugs, guns etc is all about intelligence.
I cant remember a single case where the headline stated that "due to a lucky stop and search of a light aircraft we have now arrested XXX men on suspicion of whatever". I have never even seen a customs officer at Lydd and i have made many landings there. Although Robin did tell me a van load of them turned up once and raided an arriving aircraft and i suspect that wasn't on the off chance they were not declaring a couple of bottles of Gin!
