C560 CREW AND A STRAIGHT TAIL BONANZA HAD A NMAC IN C90 CLASS E.

Narrative

AFTER HOLDING AT KRENA INT. TO WAIT OUT TSTMS AT PWK; WE WERE GIVEN A VECTOR TO THE ILS 16 AT PWK. WE WERE THEN TOLD TO TURN TO A 40 DEG HDG. WE TOLD THE CTLR THAT THE HDG WOULD PUT US IN THE WX. WE WERE TOLD TO 'TURN NW.' I ASKED FOR A SUGGESTED HDG; AND WAS TOLD TO 'TURN W.' I QUERIED THE CTLR IF HE WANTED US ON A 270 DEG HDG 4 SEPARATE TIMES WITH NO ANSWER. THE CTLR ANSWERED SEVERAL OTHER ACFT WHILE I WAS ASKING FOR CLARIFICATION; AND WOULD NOT ANSWER ME. AFTER ABOUT 5 MINS ON A 270 DEG HDG; WE GOT A TA. AT THIS POINT; WE WERE IMC. THE MFD INDICATED A TARGET AT 12-1 O'CLOCK; LESS THAN 1 MI AND 100 FT BELOW. I ADVISED THE CAPT TO CLB. AS WE STARTED TO CLB; THE CTLR CALLED THE TFC; AND WE INFORMED HIM THAT WE HAD RECEIVED A TA AND WERE CLBING. I FINALLY GOT THE TFC IN SIGHT. IT WAS WHITE WITH RED AND BLUE STRIPES; AND APPEARED TO BE A STRAIGHT TAIL BONANZA. I HOPE CTLR OVERLOAD WAS A FACTOR IN THIS OCCURRENCE. THERE WAS NOT MUCH THAT WE COULD HAVE DONE SINCE WE WERE IN AND OUT OF IMC; AND NOT GIVEN VECTORS. WE WERE SIMPLY TOLD 'TURN W.' BY BEING OBSTINATE; FRUSTRATED; OR SIMPLY LOSING TRACK OF US; THIS CTLR PUT MY LIFE; THE LIVES OF MY OTHER CREW MEMBER; AND PAX; AND THE LIVES OF THE OTHER ACFT'S OCCUPANTS IN DANGER. THE OTHER PLT ALSO ENDANGERED ALL INVOLVED BY FLYING AT AN IFR ALT WITHOUT BEING ON AN IFR FLT PLAN OR IN RADIO CONTACT.
