The title of the thread is misleading in any case.
Makes it sound like whatever took place was intentional.
I highly doubt there was anything intentional about any act - on either part.

Fairly unusual to see tactical aircraft cruising in the FLs in any case since I doubt they are RVSM equipped.
Did this incident happen near any SUAS?

Can any present/past F-16 pilots shine any light on this? Is there any Block that is so equipped?
