Many years ago flying in a friends Terrier Aberdeen to Cranfield we were passing the old Doncaster airfield when a sailplane came from behind, sat on our wingtip then accelerated off ahead. At the time I noted that we were burning nearly 8gph, and oil at about a quart an hour. It's a hard a/c to love. sorry Gasax ( It might even have been G-ASAX we were in)
