SMT X UNAUTH UNCOORD PENETRATION OF ARTCC AIRSPACE. OPDEV.

Narrative

WHILE WORKING N ARR AT IAD APCH; I TOOK A HDOF FROM BALTIMORE APCH ON SMT X FLYING DIRECT MRB VOR; DIRECT IHD VOR AND POINTS W; AT 8000 FT; LOOKING FOR 12000 FT AS A FINAL ALT. AS HE APCHED MRB; I CLBED HIM TO 10000 FT AND CLRED HIM DIRECT IHD. (10000 FT IS THE ALT WE HAND OFF TO ZDC ATC.) SUBSEQUENTLY; BECAUSE I WAS WORKING THE AFTERNOON ARR BANK; HAD 4 OR 5 OVERFLTS; SEVERAL TCA VFR'S AND IFR PRACTICE APCHS IN PROGRESS AT MRB; I FORGOT ABOUT SMT X AND NEVER INITIATED A HDOF TO ZDC. ABOUT 7 MINS AFTER HE PROBABLY LEFT MY AIRSPACE; MY WORKLOAD LIGHTENED UP AND I REVIEWED THE FLT PROGRESS STRIPS AND FOUND SMT X. I IMMEDIATELY CALLED ZDC TO SEE IF I HAD HANDED HIM OFF. WHILE THEY WERE LOOKING FOR HIM I CALLED SMT X AND ASKED HIS POS; WHICH HE SAID WAS 17 MI SE OF IHD (AND NOW IN ZOB AIRSPACE). AFTER GETTING THE CORRECT FREQ FROM ZDC; I SWITCHED HIM TO ZOB. THE ZDC CTLRS APPARENTLY DIDN'T SEE HIS UNTRACKED DISCRETE BEACON CODE GO THROUGH THEIR AIRSPACE AT AN IFR ALT OR IF THEY SAW IT; THEY DIDN'T DO ANYTHING TO TRACK DOWN WHO HE WAS.
