Typhoons in Austrian service

Flight International have an interesting article on the Eurofighter Typhoon in Austrian air force service. Their procurement was controversial having being chosen to replace the Saab Draken but since the decision to choose the Typhoon there have been many questions in the Austrian parliament, no doubt the cost is an issue but defence does cost. Also interesting are the details of Austria's "tiered approach to ensuring airspace control" using a mix of armed trainers, helicopters and ground bases.
