As the Cessna 172 taxied toward the fuel truck, there was something amiss with the marker beacon wire on its belly. It looked like there was a tree branch entangled in it. It wasn’t a big branch, but it definitely should not have been there.
A quick conversation with the somewhat sheepish CFI revealed he’d taken the learner to one of the private grass strips the flight school had permission to use for soft-field takeoff and landing practice. As they landed to the south, which the CFI noted he’d been told was the preferred runway, it felt like they had a tailwind. The windsock confirmed this. For departure they backtaxied and took off to the north.
