Boeing whistleblower raises doubts over 787 oxygen system

I remember this on a flight to an airbase in Catania, Sicily. Overnight flight, we were given drinks, then turbulence hit with the hand of Thor.

I'm pretty sure we dropped about 500 feet straight down, but all I remember was being amazed how my cup of pepsi stayed on my tray and didn't fall over.

If the pepsi was still in your cup, you were still at some degree of positive "g". Anything below about 0.5 will cause people to start screaming. True falling is 0g. But things suddenly get very bad at even the slightest negative g. At -0.1g your pepsi is levitating out of the cup, the 100lb drink cart is now airborne, and a second later it all comes crashing down.

I remember having some sort of feeling "negative-g" at that time (and plenty of people were screaming!) but we probably did have some amount of positive G. Probably not much though.
