important buildings are protected against car/truck bombs - underground garages have been closed in many cases, concrete barriers near entrances, streets closed, etc. a plane can fly into a building without restrictions.
nobody is talking about "banning small planes" - but there need to be more restrictions on allowable flight routes around major cities for sure.
I can understand why pilots will have these restricions placed on them, after all they're just a bunch of rich happy go lucky playboys, who cares about that bunch of narcistic jerks, restrict em, tax em, lower em back to the level of the regular Joe.
I got news for you, judging by your screen name I'll bet you make a whole lot more money than me and a whole lot of other pilots. Most of us *are* regular Joes tryin' to make it all work in an increasingly hostile environment. Flying's a huge part of my life and who I am, I make huge compromises and sacrifices to do it, in a monetary way and in a regulatory way too. But it also gives me as an American an unbelievable amount of freedom that most folks will never experience or understand. I can go jump in my plane and in an hour be glassing an elk in the middle of nowhere. These sorts of things are uniquely American in this increasingly restrictive world we live in, and you can be damn sure that these unique things are at the top of the terrorists list for destruction. Why do any of us (especially here!) want to grant them that satisfaction?
Constantly worrying about the hundreds of ways you can meet your maker is no way to live my FRiend. You're really asking to take another incremental step down the road to a nanny state, and you're also helping the terrorists win their little Jihad too. Stay brave, stay free.
