The stadium TFR has a 3 mile radius, up to 3000' AGL. How long do you think any plane larger than an ultralight, or a Cub, would take to get to the center of a TFR?No, the post was not a joke. It is easy to have a cynical view of the value of the TFR, large gatherings of people on high profile activities are targets.
I also posted previously I would like to see some evidence from the government that these TFR are actually beneficial to security. It’s a topic I wish a congressional subcommittee would look at.
Hint: 1.5 minutes worst case. A lot less some places, since ATC clears people through them (Disney, Nebraska football, many others). Ask yourself if that is enough time to stop a threat.
