Not hard to do the math;
Slow deliveries / Large workforce = cashflow issues.
Even with a healthy order book, Alpha needed to ramp up or shut down.
Adam in the USA has just shut down (pending cash injection).
Columbia went the same way and Cessna got a bargain as a result.
Eclipse was staring Chapter 11 in the face late last year.
None of the above had an issue taking orders - just making deliveries/generating income.
I hope the likes of Boomerang take heed and do whatever to stay in the game.
