I'll start with the 727-100 and 200. All that are currently available still have cradle-mounted wings. We need a serious upgrade..complete with aerials. Also a DC-9-10 series should be at the top of the list. Nothing is currently being made, and the ones that are out there are not anywhere close to current standards. Feel free to add any to this list as you see fit. Hopefully GJ, Phoenix or NG will step up to the plate and get some of these out there.
