Why did Condor close ?? And Kirknewton stay open ??
Hopefully this is an ironic question, but the answer will be demography. Condor is near Arbroath, Kirknewton is on the west edge of Edinburgh so far easier for the majority of the population to reach.
Spend gazillions,not fly for 4 years and end up with new gliders.
There is no glider maker in the world that could supply sufficient (over 60) 2-seat gliders in that timeframe, even if negotiations had started years before and their entire production went to the Cadets.
