3 PHL CTLRS WITNESS OPDEV AS ZNY HOLDING ACFT ENTER PHL AIRSPACE WITHOUT COORD.

Narrative

WHILE WORKING THE N HIGH POS; I WAS INFORMED BY N ARR THAT ACR X WAS EXITING THE BUNTS HOLDING PATTERN AIRSPACE AND WAS NOT IN RADIO CONTACT WITH PHL. I OBSERVED ACR X CONTINUE TO A POINT APPROX 10 MI E OF THE HOLDING PATTERN PROTECTED AIRSPACE BEFORE TURNING BACK TOWARD THE PATTERN AND DSNDING FROM 13000 FT. ACR X WAS APPROX 7 MI FROM ACFT X; A C56X ON THE JAIKE STAR TO TEB AT THE CLOSEST POINT. DURING THE NEXT 5 MINS; I ALSO OBSERVED ACR Y (A CRJ2) AND ACR Y (TYPE UNKNOWN) LEAVE THE HOLDING PATTERN AND ENTER MY AIRSPACE WITHOUT PRIOR COORD. FORTUNATELY; MY POS WAS NOT BUSY DURING THESE OCCURRENCES AS THESE ACFT WOULD HAVE CREATED AN IMMINENT SIT INVOLVING ACFT DEPARTING PHL OVER THE DTW DEP FIX; AND ACFT ON THE JAIKE STAR. SUPPLEMENTAL INFO FROM ACN 661390: SEVERAL ACFT WERE ALLOWED TO STRAY OUT OF THE BUNTS HOLDING PATTERN AIRSPACE. TO THE BEST OF MY KNOWLEDGE; NO COORD WAS MADE BTWN ZNY AND PHL. THE ACFT (WHICH WERE UNDER THE CTL OF ZNY) WERE ALLOWED TO LEAVE THE HOLDING PATTERN AIRSPACE; ENTER ANOTHER FACILITY AIRSPACE AND WERE THEN DSNDED IN PHL AIRSPACE -- ALL WITHOUT COORD. I POINTED THE STRAYING TFC TO OUR N HIGH POS. I AM UNSURE HOW CLOSE THESE STRAYING ACFT CAME TO OTHER ACFT IN OUR AIRSPACE.
