Caution have a water hose handy to deal with "Grass Fires" resulting from the scattered burning paper. Don't try this where burning paper will land on building roofs, or drift into areas conducive of "Wild Fires". Expect burning paper to be blown as much as 100' in the air depending on proper placement of paper in barrel before lighting the fire. Ralph Nesbitt Professional FD/CFR/ARFF Type |

There are now "Air Safety Directives" stipulating/requiring certain operating protocols to minimize this hazard associated with the "Boeing CWT Design Philosophy". Splaps Boy is correct in that the A/C is not a "bomb" in the conventional sense of large object full of high explosive that is gravity-dropped on a target, but a Boeing 7x7 aircraft's CWT with the right fuel-air mixture if detonated can equal several sticks of dynamite in explosive power. Please note "Splaps Boy" is the one screaming "Bomb" not be. I am simply pointing out "The Boeing CWT Design Philosophy" results in conditions in the CWT of Boeing A/C conducive to "Self Initiating FAE's (Fuel Air Explosion)". Self - initiating ? I've never known a fuel air mixture explode of its own accord outside a diesel engine. Especially with quite low temps. An ignition source is also required. Certain specified operating protocols have become minimum SOP to limit the "Inherent Danger" associated with"The Boeing CWT Design Philosophy". As in turning off the fuel pumps with the dodgy wiring when the tank is low ? Graham For details regarding the "Self-initiateing" comment above see: http://www.galcit.caltech.edu/EDL/pr...nceptions.html There are references to several scientific papers here. Effectively it is not uncommon for the "Air Temp" inside the "Vapour Space" of an A/C with a "~ empty CWT" sitting on a ramp in high ambient temp conditions with the air handling units running, to exceed the "Flash Point" of "Jet A Vapors" within the ambient atmospheric conditions. The upper & lower flammable limits of Jet A vapors vary with atmospheric pressure & temp of the vapor. When Jet A Vapor that has been heated to a Temp close to it's self ignition Temp at a given atmospheric pressure, a change in the atmospheric pressure can result in self ignition resulting in an FAE.

Duster Glad to be of service ;-) About time a.d.a talked about real a/c probs instead of crank dip**** conspiracy theories. You mean that crank dip**** Hall? The TWA 800 enquiry was so badly handled that it was bound to result in conspiracy theories regardless of the merits of the variously debated scenarios. So, basically, yes I guess so. GRaham |

An out and out lie and a conclusion which Nesbitt is completely unqualified to draw. snip of additional false statements |

Splappy you are beginning to get so far out in the "Briar Patch" beyond the "Facility's Left Field Fence" you can barely be "Heard". I am completely mainstream. It is your insistance on lying about the reliability of the 747 that is out in the ozone, Ralph. There is nothing wrong with the airplane, as it comes from the factory. Your "burning electricity caused section 40 to fall off" theory sure finds fault with the electrical fault isolation design and you accuse Boeing of installing an undocumented section to boot! Suggest you brush up on chapters 6 and 24. Undocumented in what way, Jimmy loon? Undocumented as in nonexistant. Jimmy, there is no possibility that you could know what you are writting. The truely fantastic part, is the notion of a grease monkey aregueing with a systems engineer, about how an airplane works. You couldn't be more of an idiot, Knoyle. |

![]() "Ralph Nesbitt" wrote in message m... Hopefully Phil picks this up for his section on "Tarver/Splaps Boy/Splappy. You do know, Ralph, that the spoiler is operated as a flap on 707, 727, and 747 Boeing aircraft, by the automatic Yaw damper? That is of course a predictable result, when you parrot Craig, a scab road engineer's draftsman. (crossing state lines to evade the engineer's Act) The Mazor sock mighthave been a better choice to parrot, except his puppetmaster Marron was never more that a turboprop operator.
