I suggest replacing IT with Construction and replace 'hang some coat hooks' with 'replace a hard drive' ?
But it's a simple task. I fail to see how hard it is to hang a coat hook, and if you can't/don't know how to do it then there's always google to the rescue hell I'm sure there's videos on youtube dealing with how to install coathooks, there's certainly videos on how to replace a hard drive or build a computer. Granted, I actually worked in the construction industry as a summer job doing all the odd jobs and simple things that needed to be done, but still if someone asked me to bake some pilsbury cookies in the oven it's not that hard; cut the dough up into cookie shapes, turn it on, set to right temperature, put the cookie rounds in the oven and set the timer, take it out when the timer beeps and you've got yourself some cookies. It's not like they're asking you to make a souffle or knocking down a load bearing wall to renovate the building.
I just want to clarify that this is absolutely *not* how things work in the United States.
In the US, if you're flying privately, you walk through the lobby of whatever FBO (Which is a company that provides fuel, a pilot lounge, catering, etc.) your plane is parked at, smile at the person behind the desk, get on your plane, and leave.
Jobs was right to think that he could get on the plane with his stars because, usually, he would be able to.
Even if you do it at a Fixed Base Operator you still get checked out by customs if flying internationally. Muskoka Airport (CYQA) is a port of entry for international flights and private planes that land still get checked out by Customs. Otherwise if you wanted to sneak in drugs into a country you'd be pretty much freely able to do it via FBO's and chartered private jets.
Numeric stability is probably not all that important when you're guessing.
