Boeing 707 - 35 degrees
Boeing 727 - ?
Boeing 737 - 25 degrees
Boeing 757 - 25 degrees
Boeing 747 - 37.5 degrees because it's halfway between 35 degrees of the 707 and 40 degrees that the performance guys wanted but engineers didn't.

For the other two unlisted aircraft a small cheap scale model or an aerial photograph of the planes along with na protractor should provide the answers. I wonder if the 747 series is the most swept of all the airliners flying?

I thought the 707 was so named because of the 45 degrees of sweep: Tan 45 being 0.707? Maybe a myth?
