forgive me if I have recounted this incident before....
When towing up a twoseater glider with a 150 hp supercub at Shenington, when the wind is on the ridge, I normally took advantage of the lift along the ridge, to improve the performance of the combination.
One such day, noticed a glider soaring the ridge toward me, nothing unusual about that. Except it wasn't a real glider at a safe distance, it was a model glider, too close for comfort! I smartly made a sharp left turn away from the conflict, to the surprise of the glider pilot on tow, who hadn't seen the model, but she hung on OK, and we continued on our way unscathed. Of course we saw the funny side of it later, I can just picture the angished concern of the model driver down there on the hill, not knowing what to do or which way to turn....
We used to get on with the model flyers just fine, but the farmer got fed up because their vehicles used to churn up his field, so he locked the gate, and we don't see them these days.
