OS B707 ops were indeed interesting, planes came from SN
, had JT4 engines, which made the 707 one of the really nice ones. ops didn't last long, as far as i know, there were two frames flying, one in OS
livery, the other one in SN
(might be mistaken). routs were from VIE
, maybe on certain occasions SZG BRU JFK
. but the most interesting B707 operator in austria was Montana Austria, a privately owned airline. they even operated the B707-138B... man that was intersting!!!
here an article in german only, but pics say more than 1000 words!!!
a few years ago, the pilot who funded this airline died, he was a legend in austria and a B767 captain with NG
if i am not mistaken. those were the guys that more or less successfully challenged the state funded Austrian Airlines.
