F70
The F70 is basically the same aircraft as the -100, smaller cabin (15.2 ft shorter fuselage and 79 passengers max) so they don't suffer from "Dutch Oven" problems, and they also have smaller engines (TAY 620 - 15's). The maximum gross takeoff weight is also lighter, 84,000 lbs (one executive version is 88,000 lbs.).
In the US, several airlines ordered -100's: Braniff ordered about 18, then cancelled, Pan Am picked up those orders plus added a few more, but also cancelled before delivery. US Air bought 40 (which have since been parked, some sold overseas), then American with 75 (starting to park) and Midway with about 11 (sold). The -70 didn't really sell over here, 2 sold to Ford (which they still operate) and 2 went to Mesa which were quickly sold after Fokker shutdown. Fokker tried to market the F70 as a RJ to the airlines, but I believe they were just ahead of their time. I doubt the ERJ170/190 or CRJ700/900 are anywhere close to the airplane the 70 is, at least in the cockpit.
Rumor has it that someone is looking to restart production on the -70 first, then maybe the -100: Rekkof (Fokker spelled backwards) of Holland. Rekkof has made several announcements that they plan to start production very soon, but they are having problems getting it started for some reason.
