If I was a PLANE, I'd DEFINITELY be a 757 - a 752 to be exact!
Not too big as to be bloated or oversized, but not too small. And still respected the world over
I'd be plenty powerful and the smaller ones would still have to watch out for my wake turbulence!
If not a 752, then an A340 - still long and lean with power denoted by 4 engines. And a rare sight at that! (at least in the US)
