Was about to turn in and thought to take a look at the flightradar for weird flight paths, chems, stumbled on 3 escorted flights from what look like C-100 Canadian military planes. 3 flights closely followed. 2 are headed to the detroit border. 1 is north of north bay. Q400? Might be nothing but they have switched call signs. Last time I saw this was last winter during all that RED OCTOBER stuff.
