@WR 6-3. I’m not arguing one way or the other for the FOIA request. I imagine that FAA deliberations include its consideration for details of the type design, which make a response to the FOIA at least difficult to sort through, and in preparation of the response, carefully consider its legal obligations regarding the protection of proprietary rights (trade secrets etc.). All of this adds a lot viscosity to the lubricating oil of government machinery and in no way implies reluctance to meet legal obligations of the FOIA act. Like it or not.
