As a pilot, and someone who has flown jets I found parts of this Chapter a bit... well let's just say I skimmed certain parts. I can understand that you're not a pilot and don't understand how the licensing scheme and endorsements work, or certain other things. But a few odds and ends I thought I would share, up to you if you care or not, I know this section was written some time ago.
1) A tower will never 'wave you off'. They're not flying the aircraft, unless a ground obstacle appears they don't interfere much. Now an LSU, if there is one might send you around, but that's military.
2) Jets are -way- easier to fly that props IMHO, though everything does happen a lot faster. No 'P' factor and a lot less vibration up front.
3) Flying in unpressurized cabins as you get higher is tiring. Over 20,000 feet you have to wear a full mask as you start getting in to pressure breathing where the air is literally forced into your lungs. Do that for 3 or 4 hours and you feel like you ran a marathon, it's very tiring.
4) if you've been breathing supplemental oxygen you will usually wake up in the middle of the night with an ear ache and have to pop your ears. That's because your inner ear canal eventually fulls up with a richer oxygen load than normal. That Oxygen is absorbed directly into your body thru the walls of the ear canal and you get lower pressure in your ears. The higher concentration of O2, the worse it gets. Worse one I ever got was after doing #3 above. landed, had dinner, went to bed. Ouch.
5) Oxygen is the cure for a hangover. Ask any military pilot.

6) I wish I had a rich sister to buy me a nice airplane. I haven't flown in ages because I either don't have the time, or don't have the money. Of course I'd want a jet, or an acrobatics plane. Just flying from point A to B isn't as much fun as it used to be.
Oh and I've actually been to the Cessna plant, years ago. The salesmen there dress like the salesman from WKRP (or at least used to. Bright Plaid! My eyes!). Sadly they're shutting everything down there and moving most of it overseas now.
