Commercial Aircraft or GA Aircraft can fly in a TFR if they have proper clearances and needs. John Q. Public flying his Cessna 172 for fun isn't going to get approved to fly in the TFR.well I suppose that makes more sense but aren't there major airports that are near Superbowl venues? They don't shut down airports I am sure.
We lost the Chargers but their stadium was only 5 or 6 miles away from Lindbergh Field
These TFR's for sporting events and VIPs etc aren't new at all... we just have a lot of people coming into this hobby who have no clue about such things and learning about them on-the-fly.
