Blocking 40 meant you'd use less thrust on approach and therefore be quieter coming in. There's one hush kit that has you landing with flaps 25 but I'd say most folks still land "30, 30, green light."
And all that stuff is anti iced after it unfolds except the #1 and 6 Kruegers with bleed air. All sorts of telescoping and twisting tubes.
This sounds like the most complicated wing ever designed. Was it prone to Mx issues?

The blocking off of Flaps 40 you speak of is done with a bolt (I've looked at a few -200Adv cockpits before scrapping)...a few twists and if you need Flaps 40, you can get it. (You can also still select it with the alternate flaps system.) Landing with 25 seems to limit the capability of the airplane, although in the stacks of stuff I have, I have no ODM, so couldn't tell you for sure.
Interesting. I didn't realize the 727 was THAT loud. I'm still wondering why they put these weird Krugers on there to begin with. I'm going to go try and research this.
Thanks for all the input, I like stuff like this. I enjoy learning new things. However, it makes me a bit jealous that I've never had nor probably will have the opportunity to fly one. I'd love to fly that, AND the DC-9. Call me crazy, but if NW called me up and said I could fly the 9 or the bus, I'd take the 9 every day.
