I watched ANA take delivery of their second 787 a few weeks back and within a few Hrs. I watched Cargolux do a pre-acceptance flight of their 747-8. All from a distance of about 1/2 mile. Believe it or not the 747-8 being twice the size, twice the engines, twice the power, and twice the weight, it was (in my opinion) twice as quiet!

AMAZING!
