See my on-board takeoff on a British Airways 747-400 G-BNLJ back in 2013 here: [ Ссылка ]
Here's a video showing the takeoff aboard a British Airways Boeing 747-400 departing London Heathrow Airport heading to the Vancouver International Airport. This video was taken by my Mom on her last trip to Europe. It was pretty cool that they got to board the 747 at a remote stand. The video includes a bit of the boarding process, some taxiing, and the takeoff and view around Heathrow.
