So Pete and I were doing a training yomp this morning ready for the Three Peaks challenge when we heard this strange noise... not quite helicopter but helicopterish.
Then we spotted 4 autogyros flying towards us in a diamond formation, they went straight over our heads and off.
A couple of miles later another autogyro also buzzed us! Pete and I agreed not only was the walk excellent (18.5'C and the first outing for my legs in public this year) but the free air display made it extra special 8-)
