Most of us still have not flow on the Dreamliner, including me (my first flight is scheduled for Feb 2016). I’m really looking forward to the experience.
Boeing has released a YouTube video that shows a Dreamliner going through it’s practice flight in preparation for the Paris 2015 airshow. The video runs for about 8 minutes and it gets a little repetitive, but there are three different camera angles you can watch it from and I’d especially encourage you to watch the take-off. I was astounded at what a steep pitch the plane can ascend after leaving the ground.
Here’s a link to the video: https://www.youtube.com/user/Boeing/ChooseYourView
Very interesting and what a wing shape! Have a look at this shorter clip (3mins) which appears to show a vertical initial climb – wow. We are scheduled to fly on one in October
