I've seen plenty of jet powerbacks over the years in the USA, but never with the same types elsewhere.It seems to use a lot of thrust/noise/fuel for a limited distance backwards. Possibly with more expensive fuel in Europe it's just cheaper to have a tug.
Scot Airways always did it away from the Edinburgh terminal with their Dornier 328s headed for London City, marshalled backwards. Not known another turboprop operator to do it in the UK. I've always been on the jet on the route in recent times, do they still do it with the Dorniers ?
