Sena Highman: What you are looking at is an ordinary commercial aircraft configured for flight certification. I know this, becaue my past work included designing the control processor for a special switching system for Boeing Seattle flight by a company called ITI, inc. This system was used for routing analog downlink data from aircraft in the flight test room where FAA inspectors worked. In past essays you have read me rant about V1.0 software no longer being a standard or goal in software engineering. This switching system is one such system still running V1.0. This photo could very well be of a Boeing plane, based on my knowledge of how they perform flight testing....Show more
Morris Cuomo: Orange wires, for testing, are not in shown in the factory wiring diagrams, which are a part of every military aircraft's inventory. When a "test wire" is used, it usually isn't listed, except on a "topper sheet", then they want to make it easily identifiable. Boeing has been! doing this since the '50's. When I worked for Raytheon, we still used orange wires for temporary installations. My dad helped develop the KC135 and I worked on them for 20 years. Even found some of the old test wires (disconnected and capped on both ends) that my dad installed....Show more
Hyman Coren: I've been involved in many system tests on USAF aircraft. The orange cable is used to identify it as temporary run. Once all testing is done, regular wiring is installed as part of the modification, which will have individual wire number markings on it.
