Where were they going?
Yesterday on my way back from a rather hot and bothered flying lesson in Hertforshire I was parked in the car park of the Feathers Inn in Wadesmill (just south of High Cross on the A10) at about 2:30pm when 6 Yaks (or at least they looked like Yaks) passed overhead east to west in formation at about 1500 feet. One by one they rolled inverted and then snapped back the right way around again. Distinctly impressive, but where were they headed, anyone know? My guess is they were out of North Weald, perhaps?
Which brings me to another question - would it be possible to roll my PA38 inverted (note I ask whether it would be possible, not whether it would be advisable)?
