Requiring commercial or military levels of experience before allowing pilots to fly would kill general aviation stone dead.
Yes, aircraft occasionally crash. Yes, even more rarely one of us gets killed. As far as I know, with the exception of Lockerbie (which wasn't an accident) no member of the public on the ground has been killed by a crashing aircraft in the UK since the War.
I'm a consenting adult, I know the risks, and I don't need any more nannies saving me from myself. Please go away.
