Narrative:

Dfw was in north flow. Flight was cleared on the keene SID (radar vectors). Flight was leveled at 4000 ft and vectored directly over ftw. Flight was then given a southerly heading which resulted in flight exiting class B airspace when class B floor went up to 5000 ft. Controller was queried and confirmed exit of class B airspace. He had not previously advised flight of class B airspace exit. Vectors to re-enter were then given. This area is heavily used by GA. Will it take a fatal midair?

Narrative: DFW WAS IN N FLOW. FLT WAS CLRED ON THE KEENE SID (RADAR VECTORS). FLT WAS LEVELED AT 4000 FT AND VECTORED DIRECTLY OVER FTW. FLT WAS THEN GIVEN A SOUTHERLY HDG WHICH RESULTED IN FLT EXITING CLASS B AIRSPACE WHEN CLASS B FLOOR WENT UP TO 5000 FT. CTLR WAS QUERIED AND CONFIRMED EXIT OF CLASS B AIRSPACE.
