I must admit, it was me. I was at home last Friday afternoon and was getting sick of just looking at yellow and black helicopters flying over the top of my house (Peplow airfield 5 nm E of Shawbury). I did a Blue Peter special with a coat hangar and a 12 volt battery and, before you know it, there was all sorts overhead. Didn't do it for long as the incessant noise woke the dog and he started to knaw on my ankle.
Seriously, 4 years flying in N.Shropshire and I've never had a GPS drop out. Malvern, yes; Shawbury, no.
