Heard from someone it was EBW.
I was also a little surprised to hear that they were conducting PFL's quite so close to the ground, obviously with an intention to land. Source didn't think it was one of their older instructors & quite apart from the legalities of it I understood the Canterbury Aero Club were quite keen on their members keeping away from the ground - special rules in excess of CAA regs etc? Or was it a flight test with examiner o/b, or even a strip down there somewhere we don't about (could be useful to know)?
