This is my first post to this rec.aviation.piloting so forgive me if this
has been discussed before.

A friend of mine who is IFR rated said there used to be a term called tower
to tower to allow for an IFR clearance from one towered airport to another.
This type of clearance wasn't as complicated as a full blown clearance. He
thought that the name had been changed or that it was now called something
else. I googled some but could not find any reference and not being IFR
myself have no clue.

Any comments are appreciated.
