Safety,
That has cleared up a long running mystery. Then again, I doubt that 70 miles distance would have made much difference as goes the recent debate over whether the Typhoons would be better based at Lossiemouth or Leuchars. For somewhat different reasons to a Soviet air attack on the V-Bomber Bases, I'd have thought that Leuchars still remained the most all round advantageous base for the Northern Q!?
