Like other DC-9s, its rear-mounted engines and T-tail stand out, though the Series 20's larger wing relative to its short fuselage distinguishes it from the standard Series 10.

History

Built for Scandinavian Airlines to serve short, sometimes gravel or snow-affected Nordic runways, the DC-9-20 first flew in 1968 and paired extra wing area and high-lift devices with the shorter Series 10 fuselage for better short-field performance.

Variants

Only a small batch of Series 20s were built for SAS, making it one of the rarer DC-9 sub-variants.

Where you'll see it

It served with SAS for many years on regional Scandinavian routes before retirement, and was not widely operated elsewhere.
