As someone up-thread mentioned, why not relocate to RAF Benson only 3 miles away - assuming of course any testing MB currently do at Chalgrove does not interfere with normal airfield ops.
Interestingly Wiki says that Chalgrove Airfield is very secure and "surrounded by high fences". Am curious as to why this is - surely the testing of ejector seats is not hugely secret?
And again to quote someone up-thread, what actually happens at Chalgrove now if most of the actual testing takes place in Northern Ireland? Is it now just a base for the two Meteor's - in which case they could surely be based at Benson or Northolt?
