The truly ugly planes I've seen are those old derelict wrecks that always seem to be in some corner of most any airport. Flat tires, peeling paint, yellowed cracked windows, rust, corrosion, layers and layers of dirt all over everything.
I don't know why, but to me, they are kind of fascinating. What happened that they came to such an unremarkable end, yet somehow avoided the crusher? You know it's the end of the line for these wrecks, but you kind of wish you could somehow save at least one of them. Restore it back to it's original glory. If only you had the time and money, and didn't care that it would never be worth the money you put into it.
Then you walk away and see a perfectly good, working and current airplane, who's ascetics and beauty have been destroyed by some brainless, uncreative idiot, who got a deal on purple and green paint somewhere.
God I love airports.
