Even Helgoland-Düne airport has three runways and all three concrete....which even many/most big international airports do not have....
The longest of the three is just 480 m. Maximum landing weight is 5 t.
-> No, it is a little bit too short, so by minimum 320 m..
Also a LH B737-200 made a balked-landing in 1972...perhaps we shall classify Heligoland dune airport (HGL) regarding this as "international".

Air Tahiti, obviously. There are a few other airlines in the Pacific region that are interested in using it for island hopping on routes currently served by much smaller aircraft.

While on the subject of ATR offering an STOL version, I wonder how long it'll be before certain carriers ask for an 'S' version of the 72?

Only three with 8 Dash 7?
Air Tindi with 5
Airkenya: with 2
British Antartica Survey with 1
A S version of the ATR-72; I fear. this will not work.
What is the special feature, which makes of a standard ATR-42 a STOL version? The ATR-42 has the the same engines as the ATR-72, but the maximum power is reduced. The S version has a software update, so during start on short runways, the additional power for the ATR-72 can be used. On normal runways, it will just start with 42 standard power and during flight the power will be also reduced to standard 42 levels. So no additional fuel consumption. So the ATR-42S version can be used as standard version and when needed has additional STOL features.
The ATR-72 S version would need a new engine; so they have to change/upgrade to the more heavy and stronger PW150, used in the Dash 8? This will be a big and high expensive change and a longer more expensive certification. The fuel costs will be higher, for a real limited benefit,

According to ATR they have so far received 20 commitments from operators and lessors.
Major changes to the standard version are a larger rudder for increased control at lower speads.
