UFO flies up to Blue Angel Jet during Air show practice

Was at Willow Run Airport (YIP) filming the Blue Angels practicing for the Air Show, and due to it being bright outside i didnt notice it until after i had gone over the footage. You can see in the video at the time of filming i noticed something dart away from the aircraft and tried to follow it but just figured it was a glare or something. Once i broke the video down frame by frame you can tell the object approaches the plane (above the plane) then hovers and slightly dips down, then darts up and towards the NE. I've been in aviation about 10 years and have worked as an aircraft operations lead for a charter operator, i'm very well aware of aircraft and aviation as a whole. I'm also a skeptic myself, but this one i cannot explain.
