Flight hours are flight hours, and it’s very rare to do any type of offensive air-to-air operation outside of an exercise, so I’m sure it was a great training opportunity.
Less thrilled about it as someone who happened to be on a flight transiting nearby airspace last night, and who is familiar with incidents like KAL 007.
Maybe not actually launching a missile, but 99% of the pilot job comes before the missile is launched. Going up to fight against other aircraft, doing everything up to actually launching a missile, is a daily thing at any fighter squadron. The great thing about not launching a missile is that you can practice dozens of engagements rather than the one or two oppertunities during a live fire event.
