A bit of old fashioned trust? Wow, what an amazing concept, leaving the responsibility with the individual rather than the nanny state.
It is the responsibility of the pilot to have the correct paperwork. If they fly without a medical then they are illegal. Makes little difference who you send it to!
I quite agree. I just wonder when the CAA are going to be persuaded to stop asking for proof of full medicals, return of rating revalidations and renewals, proof of insurance etc etc and just accept that we are all as honest as the day is long.
