Narrative:

Cvg class B violation. Since the airspace became effective, we have had over 50 aircraft that we have noticed enter the class B without authority/authorized. This v-tail bonanza (aircraft Y) according to the MD80 (aircraft X) pilot report on visual color and type aircraft -- including altitude, was the first that I've seen without transponder or, as I suspect, off!
