"steve.t" wrote No, I don't think there is a sufficient pressure change to cause the lighter to mechanically breakup. I honestly don't see the danger here. What am I missing? Later, Steve.T Nothing. The O.P. was talking out of his as*. -- Jim in NC |

"C J Campbell" wrote There is plenty of oxygen. It just is not at a high enough pressure to enter your blood. There is surely enough oxygen to keep a jet engine lit. Umm. Wrong. Pressure masks are only required at the very high altitudes. Below that, higher concentrations of oxygen are introduced at the pressure in the cabin, to keep blood saturation levels at an acceptable level. Take, for example, un-pressurized singles. Pressure is not needed to get the oxygen into the blood, well up into the flight levels. If you are going to do an Exxon altitude record, then pressure is needed to get the blood to use it. The jet engines take the oxygen and concentrate it at high pressure, in order to run the combustion process at high enough levels to produce useable thrust. Bad analogy. -- Jim in NC |

This TSA policy of banning 'scary' items that have any
potential at all for use by terrorists is futile and if carried to its extreme, will result in only nude passengers drugged into unconsciousness being permitted airline travel. Where do I go to sign up for a ticket? At last, maybe I'll get to sit next to that cute blonde! -Frank |

"C J Campbell" wrote Let's pour a little butane fluid on yours and we will see if you change your mind. No big deal at those quanities. At the pressure you are talking about, it will not stay a liquid very long; all will flash to vapor, quickly. Anyway, I'm not gonna worry about it, cause it ain't gonna happen. There is a better chance of being stuck by lightning while sitting in a basement. Reference this: "steve.t" wrote No, I don't think there is a sufficient pressure change to cause the lighter to mechanically breakup. Spot on. -- Jim in NC |

"steve.t" wrote: Now let me get this right. I may have my physics a bit wrong here so let me explain my thought process. Butane lighter. Cabin depressurizes rapidly (explosive decompression?). Lighter now mechanically pops apart. O2 level is below what it takes to remain conscious and the temp has suddently dropped below 30F on its way down to -??F. So, assuming that the butane lighter was full, can its contents now catch fire or even explode? Hmmmm, no, I don't think so. But, let us assume that depressurization takes place between 10000 - 14000 MSL with a cabin pressurized to 8000 and the OAT is showing -10C No, I don't think there is a sufficient pressure change to cause the lighter to mechanically breakup. I honestly don't see the danger here. What am I missing? Later, Steve.T PP ASEL/Instrument -- George Patterson The desire for safety stands against every great and noble enterprise. |

"steve.t" wrote: Butane lighter. Cabin depressurizes rapidly (explosive decompression?). Lighter now mechanically pops apart. Don't think so. Why would a drop of about 8 psi cause a lighter (which is designed to withstand many times that differential pressure) to come apart?
