CRW FLT DATA CTLR DESCRIBED OPDEV WHEN ACFT WITH NO DATA BLOCK INFO WAS ALLOWED TO ENTER ZID AIRSPACE WITHOUT COORD OR HDOF.

Narrative

I WAS WORKING TRACON DATA AND I WAS ALSO THE OCIC OF THE SHIFT. DUE TO LACK OF STAFFING; OPERATIONAL SUPVR MR X WAS WORKING S RADAR AND HE WAS GIVING A RELIEF BRIEFING TO ATCS MR Y. IN THE MIDDLE OF THE BRIEFING MR X CAME UPON ACFT X STRIP; A NBOUND OVERFLT AT 8000 FT. THE ACFT WAS NOT ON THE SCOPE AND MR X AND I THOUGHT IT WAS A POINTOUT THAT HE RECEIVED EARLIER. LATER IN THE BRIEFING ZID CTR CTLR CALLED ON THE 01 LINE AND ASKED MR X IF HE WAS STILL WORKING ACFT X. MR X XMITTED TO THE ACFT AND HE ANSWERED. ZID ORDERED MR X TO CLB ACFT X TO 9000 FT FOR TFC. THE ACFT WAS OBSERVED ABOUT 5 MI INSIDE OF ZID'S AIRSPACE; HOWEVER; ACFT X'S ACFT DATA TAG HAD DROPPED AND MR X HAD NOT HANDED OFF THE ACFT TO ZID (LESS THAN THE APPLICABLE SEPARATION MINIMA EXISTED BTWN THE ACFT AND ADJACENT AIRSPACE WITHOUT PRIOR APPROVAL). ANOTHER 8000 FT ACFT WAS OBSERVED APPROX 8 MI N OF ACFT X BUT THAT ACFT WAS DSNDING AND AT THIS TIME ACFT X WAS CLBING. MR X CALLED ZID WATCH DESK AND THEY DETERMINED THERE WAS NO LOSS OF SEPARATION AND OPERATIONAL SUPVR MR X ADVISED HE WOULD HANDLE THE SITUATION FROM THERE. I ADVISED THE ATM; MR W; THE OPDEV.
