The Boeing 747 is designed such that it can lose 5 cabin windows and still maintain full pressurization. Wow. |

Wow. It's hard to believe that this is even possible. I've never actually had the pleasure of flying on a 747, although I'll be enjoying my second 777 flight next month.

The pilot was quoted as saying they just close the outflow valve a little for each window, and after 5 windows are poked out, the valve is closed. So I guess that means there is a constant flow equivilant to five missing windows through a 747 for fresh air. I wonder how big an outflow valve each airliner has? Obviously you need to evacuate a huge volume from a 747, but I wonder if the valve on say a MD8x is the size of a baseball or a pingpong ball or ... ? |

Something tells me it'd be pretty uncomfortable sitting next to a missing window, though... ;P |

do you also know that a 747 could be flown with just 1 engine? When I was at the Boeing plant ealier this year, during the tour, the guide told us that every 747 has to go through a series of airworthyness tests. One of these tests is flying the plane on only one engine for a period of time. Amazing!

You can unlock and open the lav doors from the outside on most aircraft by using a little trick. I learned about this by watching a FA do this at one point, but now I'm struggling to remember why she needed to do so. [img]/forums/images/smiles/icon_smile.gif[/img] |
