I've seen fighter planes go straight up at considerably more than 70 mph. Aren't airliners typically at 30,000 ft within a half hour of take off? What's the initial rate of climb out of Zurich or out of Orange County after curfew? Sure feels like more than 2000 ft/min for a while.

Don't tell that guy that a F-15 has a 50,000 ft/minute rate of climb.
Here's the climb rate for an A320:

Climb Rate:
•
Takeoff to FL200: 2,400 ft./min.
•
FL200 to FL300: 1,800 ft./min.
•
Above FL300: 1,200 ft./min

I'd be inclined to go with the updraft scenario. maybe they got too close to a thunderhead.
A climb rate of 6000 ft/min would put all kinds positive G's on the structure. It also depends whether the pilot is pulling 6000 fpm or wind gusts are pushing the plane up, then you're dealing with negative G's.
