Well, we talked to Ryan Graves, the pilot that you just heard from, literally as the first part of our road trip, as part of our Need to Know podcast.
And yet that's exactly what this pilot Ryan Graves was saying.
And what Ryan Graves' evidence shows is that it is a national security issue.
And what's really interesting is that it's intensifying. Ryan Graves has said this to us, that there's increasing frequency of these sightings now.
