That's getting to the point where they make real money (maybe $50mm/yr?) and have a serious shot at profitability.
They have at least 500 employees -- figure $100k/ea loaded cost, only possible since I think a lot of those employees are not engineers. That's all of it right there.
They really need to be in the 50b/yr range to be doing well. OTOH, they will probably get there in a year or two, and I don't see their costs going up much.
Don't think there's a formal connection between him and McAdoo.
