As far as out-witting the US intelligence system, that happens. You think if it was that easy to catch these people that they would need to tap into phones, emails, etc...? No. It's difficult. Very difficult. The sheer number of real plots, false leads, and other information that they have to follow means things fall through the cracks. Do you think the Boston bombing was an inside job as well? What about the London bombing? These things happen.
You think out-witting airport security is difficult? Even today, we constantly hear of all sorts of crazy items that slip past the TSA... and this is TODAY. Back before 9/11, security wasn't nearly as tight. Remember when people who didn't have a ticket could go through security and hang out with their friends/family at the gate until they left?
Flying skills top air force pilots can't emulate? What the hell are you talking about. It you have basic flight training, you should be able to pilot an airliner into a massive target. It's not like they had to fly through the trench and hit a 2-meter-wide target the size of a Womp Rat...
The only people who insist that the buildings shouldn't have collapsed into their own foot-prints are those who don't understand how physics works, or the structure of the buildings themselves... so no, you aren't following the laws of physics or common sense.
Many performance vehicles have this setup these days. It's an active exhaust system that allows the vehicle to remain quiet during every-day normal driving, while still being nice'n'loud when you romp on the pedal. That way you can have a meaty, throaty, bad-ass sounding engine note without consistently pissing everyone off. The valves open at higher RPMs / throttle position.
The Gallarado is a good example (watch from 3:00 - 4:00):
This tire was at 40 psi, so there was pretty much no difference when stationary. And again, this being at 40 psi, you wouldn't want to see what it looks like at 30. But yeah, obviously tires roll more than that - especially if the car is heavier than mine, and the tires aren't jacked up, but I was just pointing out that I've noticed a lot of roll just on my Outback's not-terribly-grippy, old, all-season tires, so surely in LFS I can see at least the same deflection occurring if not more (even if the tires have shorter sidewalls.)
It wasn't supposed to be an end-all-arguments photo, lol, just an example of what I have experienced in my occasional fun days.
Here's another example of mine (in a Toyota Yaris.) A very light car on crappy stock tires, and yet a significant amount of tire roll (though again unless you knew how the tires looked when they weren't flattened, this likely doesn't help much, though it should be obvious that what looks like a low-profile tire is nothing of the sort, lol.)
You should be able to notice that the front right tire's sidewall UNDER the rim is about half that of the sidewall ABOVE the rim. Lol, I had rub marks pretty far down the side of the tire.
EDIT: Here's a MONSTER version of the image. You can tell the front tire is rolled quite a bit. On the front tire, there is a dark grey band which is just part of the tire design. At the bottom of the wheel, that band is almost against the pavement, whereas at the top it's clearly NOWHERE near the tread and closer to the center of the tire.
One of the things I like about my trusty old automatic Subaru. Plenty of options when it comes to gears. A lot of cars these days just have something like PRNDL, but I've got PRND321. And since I've only got 4 forward gears, I've BASICALLY got control over all of them, lol.
If you think that's bad, try doing what I do. Spend a few hours messing around in the snow, then go for a drive the next day only to realize that all the snow packed into the wheels/axles/etc... has become frozen blocks of weight, lol, couldn't even go above 50 mph once for a few days the vibration was so bad.
