I work in aviation and it would be like an aircraft getting to the end of the runway and finding out that Bernoulli's principle doesn't work every time!
Hi Steve
But it seems that Bernoulli's Principle (which is only a theory), is a misconception, or at least too simple on its own to explain why planes fly. If Bernoulli's principle were correct then planes flying upside down would surely hit the floor quite rapidly.
Here are some interesting articles about Bernoulli and its incorrect application to Flight and Lift:-

You'll notice that I've not tempted to use any articles by Alex Jones, the references are from respected sources, such as NASA.
I'm not a specialist on any of this at all, just found your answer interesting and had a quick look.
What it does demonstrate is, after 100 yrs of flight, we still don't truly understand what 'Physics' really is, and, for this reason, why is it not possible, that a 'karma' principle, or 'effect' or 'equation' is discovered tomorrow, and rapidly becomes 'mainstream physics'
Bernoulli Principle is nothing to do with the lifting of an object, its primarily focused on fluid dynamics, and, in 1750, the thought of making a flying machine would have been considered by many to be complete quackery. Today's quackery is tomorrow's physics, and tomorrow's physics is later disproved, as humans are not all-knowing, and surely will never have total knowledge. Physics, and other sciences are just as much about tradition, beliefs, mis-conceptions, fashions, even politics, and simply the limits of human understanding.
Think I am straying off topic a little!!

I'm in Bangkok (Sukhumvit Area), still no sign of flooding here. But its more than 2 weeks since water was on the shelves of any supermarket, and many other essentials are becoming more difficult to find. No sign of water from my office window, but for sure its getting closer.
