Vfw 614
Back in the 70's, a VFW 614 used to spend a lot of time at Patchway doing M45 development flying for Rolls Royce. The overwing engine mounting seemed to make sense for all sorts of reasons, so I'm a little surprised that no-one else has tried it. I'm not sure if ever went into commercial service, but I did see one in Luftwaffe colours several years later
