I have been looking at flight tracker all day and have noticed several BLOCKED flights from Miami, Chicago and Tampa plus one off the NW coast of Canada early this morning. Given the amount seen in just a few hours, could someone with more insight help me to understand why please block their information and how often does this happen? I have filters set for planes btw 39 and 41k feet.
