content: Neat. Many years ago I've been in a similar flight simulator but that used COTS (commercial off-the-shelve) ethercat modules. These are pretty cost effective and suitable for hard realtime control (even when using Windows as an OS).

Sat in the desert for 3 years, then got cut up for scrap. So I guess there's no demand for 747-400, even with low hours - airlines prefer 747-8 for passenger service, and the remaining -400 are mostly being used for freight.
