Nice to see the Hastings thread pop back up. The last time I saw one was at Lindholme while on UBAS Summer Camp in 1969. I presume it was a T5.
A Hastings nearly caused my flying career to come to an early abrupt end in September 1966. I was flying a Piper Colt with my instructor, heading west between Reading and Newbury at about 2000', when a dot in the distance suddenly morphed into a head-on Hastings that flashed over our heads before we could do anything. It was so close we both ducked. That was the closest I have knowingly been to a mid-air.
