Aviator,. .Please excuse my attitude, its been a long night!. .with regard to your comment, when would a fire pick the right time to break out?? After all scheduled pax services have taken off and are safely en route?? Fire does and will happen whenever, however and at a time you never expect it. When would be a convienient time with you to conduct an evacuation under full working circumstances??. .Am i making my point now????. . <img src="rolleyes.gif" border="0">
