"Fly Baby, you violated Class B Airspace"

He's not ATC, so there's no rap to take.

Dozens of pilots on 122.8 heard someone say that a Fly Baby violated the Class B
at the south end of Sea-Tac Class B. If ATC *did* notice someone cutting across
the airspace and the FAA started an investigation, no doubt someone might tell
them, "I heard it was a Fly Baby." If the guy making the radio call had been
the guy who cut across, he's just misdirected the investigators.

File the NASA form, Ron. It's cheap, easy, and may protect you. We
did one, once, when Mary was dumped into Class D by an approach
controller.

My understanding is that if you file the form, you're maybe relieved
for the thing you report. How is being relieved of responsibility
for not doing anything (which I presume is what you would
report) going to do any good? The alternative is to say that
you _did_ do something that you didn't. Which seems like an even
worse idea.

Of course, if he decides he might have actually busted class B,
that's a different story, but he seemed pretty certain that wasn't
what happened.
