The sound of the huge Merlin engine echoed through Valley Township Saturday morning as a World War II era P-51 Mustang made several low passes at the Chester County Airport Fall flying Festival. Chester County Airport (MQS) is on Route 30 just West of Coatesville. It's also called G.O. Carlson Airport, after the steel company which once dominated the town. The show featured many of the aircraft based on the field-- everything from a Piper Cub on floats that spends the summer in Northern Ontario to 2 Cessna Citation business jets. Quite a few planes flew in too. Sikorsky sponsored the event and had on of their S-76C's on display. Another S-76 in Bristow Helicopters colors made a low pass while returning from a flight test. Sikorsky's big Heliplex is located at the end of the runway just across the road. Photography is tricky in the morning at MQS because you're on the North side of runway 29/11, but good sunny shots can still be had. As always, enjoy the photos and look for my blogs on PANewz.com too.
