Fighter Jets Landed at Scottsdale Airport?

At around 1:35pm today, 4 fighter jets (either F-18 or F-15) can in for landing approach over my house today for Scottsdale Airport. Anyone else see this? I have a video of one of them. They were not armed - wondering why SCF? I know in the past we'd get a single visitor from time to time - but never 4. (unless the pair came around twice...)
