i am currently the crew chief on 64-14854 and there are several things on this plane that i am trying to figure out, first is the lox servicing door on the left hand side of the nose. there is nothing behind it anymore, but it does look like there use to be brackets, there is one bracket that is the same as the righthand side lox bottle that holds the servicing/vent lines in place. so if anybody has a clue to what this is all about it would be helpful, also the flare tubes in the cargo door stick out and have shrouds on them is this normal for the original style flare tubes? i'm use to seeing the style on my previous plane 69-5832. also there are what appears to be two cannon plugs to the right of the flare tubes that are on the exterior of the aircraft what are they used for? oh yeah and one last gee wiz question there is a light behind the left hand scanner seat looks like a leading edge style light bulb... it's big, i have checked the bulb it is good, i have turned on every switch but the light will not come on, is there something i'm missing about it? thanks.
