+1 for the foe-camp.
I happen to be exactly as old as the Boeing 747, and in my not so humble opinion, the 747 represents men's single greatest achievement of all time. It even trumps a moonlanding by far. It's one thing to blast 3 people with several million pounds thrust into space, while closely being monitored by several hundreds of people. It's entirely another to transport 300 people safely across continents for over 4 decades, while theoretically being controlled by a single pilot.
It's majestic beauty has a certain appeal emphasized by the sheer wonder of such a large mass of men-made steel and aluminium slowly rising off the tarmac into the air.
And I have personally experienced the wonder throughout its lifetime. When there still was a first-class, which served champagne before take-off. Being a kid, I had to fly unaccompanied over the atlantic, which, at the time, meant I was allowed to sit in first-class so the stewardesses could keep an eye on me. They let me drink champagne…!?
Not to mention that stewardesses in those days weren't exactly an eye-sore. Yes, I'm very likely biased because of it.
So, I don't like the excessive sky-pollution it can cause in western europe, but I immediately have to admit that i absolutely loved what it represents. And that is love in past tense, because with all due respect to aero-space engineers these days, a plastic airbus which just cramps more people in less space with even less comfort, isn't exactly what dreams are made of…
I have passed on photographic opportunity several times because of this pollution, but sometimes, very rarely, it contributes to the theme.
