Narrative:
There was apparently an unauthorized and accidental incursion into class B airspace on takeoff from north las vegas airport. It seems to have been caused by a directional gyroscope that ceased working and an inaccurate or inoperative altitude indicator. Both are being checked. The directional gyroscope had previously been precessing some, but totally failed on takeoff. The altitude indicator is as yet undiagnosed and came without warning.
