What's the point of ATC if they aren't going to help?
They can't help if there's no service at all...
I guess "Good bye" at the end of the message means : "Radar service terminated, Control Service terminated, Information Service Terminated".
Should we also understand "Alert Service terminated", as the VFR flight plan was not filed (because not expected) ?
I believe IFR cancelation is (or should be) only on pilot's request...
If there was any ATS on the route, one would expect "You may contact the Information Service", or anyone who's in charge of the area.
Maybe, "procede VFR" is a local version of the "join" instruction. The one we give to cross own-nav a non controlled area. But Information and Alert Services are still provided, we don't say "Good bye"...
Seems weird to me.
