Other way around. iOS uses some of the user space GUI components of Mac OS X, but the kernel is entirely different. Android is the other way around in that they use the Linux kernel but completely re-implemented user space.

I believe it's less of that, but the fact that Facebook has enough investors (I believe the number is 500, but don't quote me) that it's pretty much reached the point where it needs to file all the paperwork with the SEC as if it was a publicly traded company. As such it really makes no sense not to do it since at least they can raise extra capital since they'll be forced to file the paperwork anyway.

shutting off a single power plant is not going to cause a major systemwide blackout assuming the high voltage electrical protection was designed correctly

Brave assumption..

Trained yes. Always succeed, no.

Depends. There are parts of the wing that are actually not load bearing, but exist for the safety of the ground crew or to further improve fuel efficiency. A crack in one of those parts would not be life threatening. Without knowing where the crack is it's hard to say whether it's superficial or not.

Yes, there is. You have to remember that the incident you link to above was over in like 2 minutes before anyone could react, but the hijackings to Cuba were continual and on the TV over and over and over again, so the default "hijacking" scenario was the plane goes to Cuba and then everyone gets released.

It was common enough that it was considered a normal thing to put on the TV as a sketch comedy skit.

I'd rather just have it unencrypted as an access point, there is less trouble that way. If you're using a 3rd party for your network transit you can pretty much assume that it's insecure. If you're really worried run a VPN over it.

Memebers of Congress in their function as officals of the US Government sued and were told that they don't have standing. Since the amendment just covers Congress and no the Executive the AG cannot sue either.

Yearly COLA adjustments. This is what members of Congress sued over and were told by the Supreme Court that they have no standing.

Is it common to request work in a warzone?

Yes, mainly because it pays really, really well compaired to other jobs in the IT industry for the same level of work. Granted the hours are usually horrible (12 on/12 off for months at a time).
