Personal opinion only, but I think that John Anderson was sold a pup with respect to his 'radar direction letter'. Mr Anderson seems to have swallowed the argument that:
* there's no C airspace in the US that doesn't have radar
* therefore, we can't have airspace classified as Class C without radar
* because, if we do, then it's unsafe
If someone can point me to a definitive source, as opposed to opinion, that states Class C without radar is a no-no, I'd appreciate it.
Call me a dumb-bum, but I still cannot understand a logic process that says Class C without radar, where all traffic is known, is unsafe, whereas Class E without radar, where all traffic is not known, is perfectly OK.
