Yes, Mad Jock, all of the above may indeed happen, however aviation will not grind to a halt for long, people will still want to travel, and rear-ends will be required to flatten the sheepskin up front for a while yet. Some of us have been through, indeed, TRAINED through similar to your list, and are gainfully employed to this day, albeit with a few blips on the employment ECG.
By the way, you left out "Global Pandemic" and "Major Asteroid Strike," assuming you want to differentiate between an asteroid and a comet, that is?
