ACR NMAC WITH BANNER TOW OVER OSU STADIUM.

Narrative

NORMAL VECTORS FOR ARR AT CMH LNDG RWY 10R. JUST BEFORE HDOF TO TWR FOR A VISUAL. FINAL APCH CTL SAID 'NUMEROUS ACFT IN THE AREA OF THE OHIO STATE STADIUM.' AS WE ROLLED OUT ON FINAL WE SPOTTED A BANNER TOW ACFT GOING UNDER US; WHICH WAS NO CONFLICT. INITIAL CONTACT WITH TWR HE SAID '6 OR 7 BANNER TOW ACFT IN AREA OF OSU STADIUM.' WHILE CONFIGURING FOR LNDG -- INSIDE ARLIG -- WE NOTICED 2 OTHER BANNER ACFT -- 1 GOING IN FRONT OF US; AND A YELLOW ACFT ABOUT 400 FT TO OUR R AND 400 FT LOW. I HAD ALREADY LEVELED OFF ABOVE THE ILS GS UNTIL I HAD A BETTER IDEA WHERE THESE 6 OR 7 ACFT WERE WHEN WE SPOTTED THESE 2 ACFT HAD I BEEN ON THE GS; WE WOULD HAVE HIT! TCASII NEVER DISPLAYED ANYTHING. ALL ACFT SEEN WERE SMALL; OLDER OR HOME BUILT ACFT WITH FABRIC SKIN AND PROBABLY NO XPONDER. WHEN MY FO TOLD TWR THAT 'THINGS WERE A LITTLE CLOSE OUT THERE' THE TWR RESPONSE WAS SOMETHING LIKE 'YOU KNOW HOW FOOTBALL IS.' LATER I TALKED TO TWR AND FOUND OUT THEY HAVE NO COM WITH THEM OR CTL BECAUSE THE STADIUM IS OUTSIDE THEIR AIRSPACE. IT SHOULD BE NOTED; THE NEAR MISS CAME WELL INSIDE ARLIG WHICH PROBABLY PLACED THOSE 2 ACFT IN THE TWR AIRSPACE. FOOTBALL SHOULD NOT TAKE PRIORITY OVER SAFETY! I RECOMMEND: 1) THIS ACTIVITY NOT BE ALLOWED IN THIS AREA: OR 2) IF ALLOWED; RADIO CONTACT BE MAINTAINED WITH TWR AND ANYTIME TWR LANDS TO THE E; BANNER TOW ACFT BE RESTR FROM THE STADIUM AREA.
