The thing isn't that Bush is showing up. It's the BS that is associated with him being there. You know what the response of the Homeland Security department is to the fact that terrorists hijacked four transport category aircraft on September 11, 2001?
Their response is to essentially shut down three general aviation airports near DC, one of which was where the Wright Brothers themselves gave flying lessons to Army pilots. If you want to fly there, you need to get cleared by three government agencies and then go down to the FSDO for an interview and then get fingerprinted.
Think you're done after you're cleared? Nope. Now you need to file not just an ADIZ clearance, but a FRZ clearance. You need to contact the Potomac Tracon on the phone -- no calling clearance delivery on your radio when you're ready to take off -- and get a squawk. And then your flight plan is sent over to the Secret Service and the TSA and NORAD.
For what? The longest runway at the three airports that are suffering from this nonsense is 3,000 feet long. Oh, yeah, at that airport? The air wing of one of the local police departments is headquartered there, so I don't know how much more security you want than having a police station right on the damn field!
The last guy who busted the Presidential TFRs was classified as a non-threat by every single agency involved. So why not just stop screwing around with these TFRs that only penalize GA but do nothing to make the President more secure.
I could make a smart ass comment about the current administration and its misguided response to various security threats, but I won't.
