I filmed it with my iPhone 6 plus, it was on a Delta Airlines flight from Salt Lake City non-stop to Atlanta Georgia on a very new plane, the Boeing 737-900. We hit bad turbulence & I got my phone out as fast as I could, most of the bad turbulence happened before I was able to dig my phone out of my bag stowed under the chair in front of me, but I did get it out & in the video the flight attendants were struggling & one had fallen down in front of the cart, they worked hard to put all there stuff away as the pilot ordered them a minute or two before my video in a message over the radio to the plane he said something to the effect of "Flight attendants discontinue service now & stow all equipment, the fasten seat belt has been turned on please remain seated as we are going to be experience some moderate to heavy turbulence as we fly around this storm system." The flight took place on Thursday June 15, 2017 on Delta Flight 2620 with non-stop service from Salt Lake City to Atlanta Georgia, flight scheduled from 4:55 pm to 10:44 pm. Airplane was a new model nicely finished Boeing 737-900, I have some still pictures from the flight & plane if you need them. We were heading to Atlanta for my daughters 12th birthday present to take her to the Atlanta Aquarium, the Cocoa Cola Plant, & to see an Atlanta Braves Baseball game at Sun Trust Ball Park. It seem like we were about 1-1/2 hours into the flight, I am thinking we were east of Colorado, but I don't know specifically.
