With Wencor`s connections in the aircraft parts world, I would think they could manage to get their hands on an old 707 hangar queen (use it for cost of storage). Then install a demo digEsytem in Spectrum seats as a showcase for potential customers, as well as proof of concept, testing, etc.
But could be a contract. Just seems that if they had a contract, they`d have just said so (though I realize the quote may have come from a less than orchestrated conversion).
