The program is moving along. Some say very slowly, some say normally for a new acquisition aircraft. I wasn't around, but I've heard when the Falcon's came online back in the 80's that they had some of the same issues the CASA (or should I say "Ocean Sentry") is having.
They just had their first SAR case off the coast of Florida when 2 F-15's crashed and found a survivor. Not a bad start to the program if you ask me.
From what I hear, the aircraft is flying as it should and is by all means safe but all of the fancy bells and whistles concerning the sensors need a little ironing out.
