... one of the JFK approaches. It's not common to see planes overhead. About 15 years ago, my dad started tossing layers of insulation in the attic, and putting in new windows (Anderson). Since then, jet noise hasn't been much of an issue - you just don't notice it indoors. The local Lilco plant dumping steam, yeah, we hear that :) BTW, only the 707 and early DC-8s were turbojet (...

...jet airliners and other jet aircraft since the early 1960s. That video had 5 different shots of trains going by that overpass, and the farthest was about 100 meters from the train. The noise sounded reasonably similar (including its volume) to a fighter jet or airliner zooming overhead at about the same distance. Bwaahahaha, that's the funniest thing I've read today. Do ...

... the trains to look good. Exactly what case is it that they "made convincingly"? That trains make significant noise as they pass? Is that something that someone needs to be convinced of? How do they make the trains look good? If you are referring to noise, I think you will find you can control that with the volume control on your computer. Merritt
