Sheffield Partenavia P.68
Has anyone any idea what/who/where/why? a Partenavia P.68 has been flying a reciprocal slightly northeast/southwest pattern over Sheffield, appearing and disappearing about every 5 minutes, so not a very large distance.
It has been flying it for the last 90 minutes or so, and it was also doing it through the Bank holday last weekend.
No probs with it, I'm an enthusiast, I just wanted to know.
Thanks in advance.
