Did any other airlines than SK use the DC-9-21? As far as I know, it's the -10 fuselage, -30 wings, and-40 engines, giving it the nick name DC9 Sport. Also, anybody know where they went when SK retired them in 99? I found pics of one that went to Aeropostal, anybody know any others?

Only ten DC-9-21's were built, all went for SAS. What happened to them after SK retired them, I don't know. Nice birds though.

Valujet, Spirit and Allegiant all operated ex-SAS DC-9-20s.

Allegiant, Aeropostal, Nordic East, Summer Express, Valujet, Spirit Airlines, and Air Alpes all operated DC-9-21s at one point. There is also a military systems manufacturer that uses a DC-9-21 for testing and has even added an inflight refueling probe.

Valujet only operated the DC9-21s for a year (give or take a few months) After the crash, they went bye-bye.

What were the advantages over the -10? I understand the better engines, but how to the wings help?

It had the wings from the 30 series, which gave the a/c better lift and shorter takeoffs.

From A.net Aircraft Data and History section:
"The DC-9-20 featured the DC-9-10's fuselage with the 30's more powerful engines and longer span wings, giving better hot and high performance."

The wings were probably more efficient, allowing a bigger tankage etc.

When SAS bought those 10 DC-9-21 in the late 60'es, then they didn't really have "hot and high" in mind, but rather "cold and short".

They were bought for the need to operate on short fields in northern Scandinavia, which are often snow or ice covered half of the year. That called for a powerful, lightweight plane with a wing with good low speed performance.

The "DC-9-30 wing" on the -21 is a much more advanced thing than the DC-9-10 wing when it comes to high lift devices. The -10 wing is probably the most "primitive" wing ever mounted on a jet airliner. The -30 wing is an entirely different sort of animal.



Always keep your number of landings equal to your number of take-offs, Preben Norholm

The main difference between the DC-9-10 series and the DC-9-20 series are the leading edge slats on the -20's.
This gave the airplane lower approach and take-off speeds and better stall characteristics. Also, there had been a couple of DC-9-10 accidents due to icing, I don't know if the new wing would have been an improvement there; I don't know of any DC-9-20's or -30's having a similar event.
The DC-9-20's had JT8D-9 engines which generated 14,500 lb of thrust to higher ambient temperatures than the -7's or -1's that the DC-9-10's have.

They also have a slightly longer wingspan and therefore more wing area/lighter wing loading.

The -10 could have JT8D-9 engines hung on it but they had to be operated at -7 power.

Spirit Airlines leased -20s in connection with a plan to run business routes between LGA and Detroit City Airport. The -20 had the juice to fly from the short City runway. Unfortunately, the plan cratered when the LaGuardia neighbors complained about noise (they would have been Stage 3 aircraft btw).

Spirit operated at least one -20 for a while.
