Didn't know that Collins had gone out of business... wow... every B1900, King Air, 737-500, and lord knows who else operator is screwed. But I have to ask the question... what about them needs upgrading? I like them just the way they are. Also think about this... do you think Silver Airways would be taking on airframes if they were going to have to upgrade the avionics just after getting them on property? I think this is a bit too much hype... but Jesus knows I have been incorrect in my mental calculations in the past.
