I read the post as 'kill switch' ( notice the colons around it ) not as an actual switch, but as a metaphor for the automated logistics system, ODIN ( which has replaced the problem ridden previous system ), that can cut off your spare parts, and software updates, at any time rendering the aircraft you paid good money for, worthless.
I guess if you have a problem parsing other poster's comments, you tell the mods to 'clean up' any responses you don't agree with.
The situation is, our current jets are falling apart, the Gripens can't do the job, and the F-35 is a 'hot potato', politically if not operationally.
Not that I would prefer Canada buy Gripens; they are woefully inadequate for what will be asked of them, but a decision needs to be made soon.
