3 St. Marys Police are stepping up patrols after vandals sneaked onto an airport runway...and caused thousands of dollars worth of damage. They say someone smashed these glass runway marker beacons in the middle of the night. Now, the airport has been forced to shut down flight operations after dark. Channel 4's Vic Micolucci spoke to airport's leaders...about the security issues.. 3 3 00-05 1'01"-1'06" 1'31"-1'36"VIC LOOKLIVE IN: If you were to walk around all the runways here -- you'd hike about 4 and a half miles. This place is not fenced in... because it'd be too expensive...the last estimate was for about a million and a half dollars. And that leaves it vulnerable to vandals...like the ones who did this.---------- 24:03 "it had to have taken some time given the runways are a mile long each." Jay Stanford is in charge of St. Marys airport ... is now tasked with having to fix the damage. 23:48 "vandals came and took the globes off the lights and actually threw them into the center of the runway. and created a large debris field in the center of the north-south and the east-west runways." It's not just an inconvenience...it'll cost the city run airport about 12 to 15 thousand dollars to repair. And broken glass caused serious damage to a plane here as it was landing.25:21 "what happened was a king air, which is a twin engine turbo prop, a businessman flew in, landed on one of the runways, and kicked some of the glass up and actually damaged some of the aircraft. and we haven't gotten the bill for repair of that but we are liable for that also." Stanford says this is first time he knows of a crime being committed against t he airport...besides trespassers who walk down the runway every once in a while. There are many entrances that aren't gated...and a full-time security officer or a fence around the property would be too expensive. Police patrol from time to time...but still problems like this can happen. 20:34 "not too many people come in and out of here, but we see a fair amount of aircraft." David Webb has run his airplane upholstry business on property for nearly a decade. He says he's always felt this was a safe little place...but now he'll be a little more careful.21:47 "everyone has full access. there's no gates here. no real security. the security late at night might be me if i'm here working late." ------------- Vic looklive TAG: The airport's managers say they'll probably have everything fixed and back to normal in about a month...after they fork over a good bit of money. They say they've asked police to step up patrols so something like this doesn't happen again.In St. Marys, Vic Micolucci, CH4, TLS.
