Passing overhead on a training flight in the pattern near Trenton-Mercer Airport (KTTN) in Ewing, NJ while I was at the rail station. The high-wing light airplane came by a few more times & I missed a helicopter earlier due to bad timing & a blocked view.
Aircraft: Cessna 172S Skyhawk SP
Altitude: About 700 feet
