Why do some of the older planes have windows looking further up than just the windsheild? I see the newer planes only have a windshield, without the smaller, "up" looking windows..
Ummmmm...Wasted said:The eyebrow windows had nothing to do with traffic. The original purpose of the eybrow windows were so that navigators could shoot stars with sextants for celestial navigation purposes. Do realize that these planes, 707s, 727s, 737s, etc. were all developed in the 50s and 60s, before GPSs, or IRSs became commonplace for long range navigation. Since hardly anybody shoots stars anymore, their functionality no longer meets the expense of manufacturing.
Thats too funny. A friend of mine was a former KC135 commander. A crewmember would always come through and collect the hard boiled eggs from the box lunches and launch them over whatever city they may be departing. After the brass nixed that, he found that a little baby oil on uncooked egg shells worked quite well. The crew chief wasn't pleased with all the splattered eggs along the fuselage and tail.TonyC said:Ummmmm...
The sextant port was used (is used) for "shooting stars". The sextant port was located in the "ceiling" aft of the engineer's station. The sextant port is a hole, slightly smaller in diameter than a chicken egg. When a boiled egg is held up to the opening, and the sextant port opened, the differential pressure at altitude is sufficient to propel the egg a significant distance away from the airplane. Don't ask me how I know this.
The vacuum cleaner was an officially condoned use until a few incidents of interference with the Q-inlet on the leading edge of the vertical stablizer. The purpose of the Q-inlet was to provide artifical feel, based on airpseed, to the boosted rudder.FearlessFreep said:A handy vacuum cleaner - that is until all sorts of paper clips, staples and who knows what else was found embedded in the leading edge of the vertical stab.
I hear that having the port open is pretty loud.
