Great Thread YF222000,

And thanks to the professional pilots on this forum for the answers.

I too am always amazed to see a large airliner take off. Watching 400 tons of aluminium, fuel and citizens accelerated to over 150 mph, and then be lifted into the air. When seen close up, it still looks like magic, even though I well understand the science.

(My wife thinks I’m a nerd when I go on about it)
