Here's a photo I took a few years back. It's Mt. Fuji. I was in a C-130 taking photos out of the jump door. I was an avionics (communication and navigation equipment) mechanic, we all used our phones and electronic devices with the ok of the pilots (some were a little more old school about it) I've never seen any interference personally, lord knows we tried! But I agree with slower flying planes being the best for photography. I tried to take some photos out of a C-17 and they turned out crappy. (C-130's are much slower than C-17's)
