Think you should be careful here. It does not say that they 'cancelled an order'. Rather that they have decided not to purchase F-35s as was their plan.
@mastodonmigration @alexlunaview Effectively it is the same thing. Lockheed knew that order was in the pipeline, even if it wasn't signed, sealed, and delivered yet.
That may be, but give the gravity of the news we should be very careful with accuracy.
