This is a view from my flight to London last night / this morning. I left Washington DC around 10 PM, but didn't arrive in London until 10:30 AM. I happened to wake up just before the sun came up - I think it was around 3:30 am (home time, or GMT -5), but was over the middle of the Atlantic the time.
Coincidentally, there was another airplane about a half mile away heading in the same direction, but I couldn't get a good picture with my phone's limited camera.
