Wow! What a coincidence!
A while back in late August or early October, can't remember the exact date, I spotted a red and white Cessna 172 (G-BAEY - also Skytrax) doing the low and slow thing over my area in Wiltshire for ages. There are plenty of good fields nearby for emergencies so can't say he wasn't obeying rule 5 - in fact one of them is a microlight farm strip.
Not sure if it annoyed the neighbours but it sure amused me
He wasn't very loud at all with the engine at quite low RPM. I reckoned that it was a photgraphy mission since the area I live is all new houses (image below). Haven't had anybody at the door trying to sell us any pictures yet.
The coincidence was later that morning I drove up to Kemble for a flying lesson and who was doing his engine checks in the runup area at the same time as me? None other than G-BAEY of Skytrax
This is a photo that my girlfriend took whilst on a trial flight with me just prior to starting my PPL course. We're over our home but somewhat higher than Skytrax were and our picture comes with an arrow pointing out the house!
Oh by the way - I am in no way criticizing this company - personally, their activity didn't bother me, in fact I enjoyed watching it.
