I believe this was well known and told to us by Oscar many times. BTW where is Oscar?
Just a joke. It doesn't make sense for any agency (like NASA) to certify our NGF design. It probably just means PAC made a preliminary design that was circulated with potential partners who thought it was a viable design. The other partners will probably propose preliminary designs of their own. There will probably be long deliberations and a final design will be selected. I doubt we can afford prototypes for each design. This is preliminary design anyway.
