OK,
first a little primer on the players:
"Little ACE" is Alaska Central Express. They operate Beech 1900's. They are operated by the Bergt family, Neil and his son Mike, of MarkAir and MarkAir Express infamy.
"Big ACE" is Air Cargo Express. They operate DC-6's and Curtiss C-46's (not C47's OtterFO, that's a DC-3). It's a bit confusing, as the names have the same acronym and they sit next to each other on the ramp at ANC but there is no connection at all between Air Cargo Express and Alaska Central Express.
Now, regarding the bankruptcy:
Alaska Central Express ("little ACE") is the one that filed bankruptcy. They are not bankrupt at all, I believe that they are in good financial condition. Filing Chapter 11 was merely a legal manuver to forestall a court order that would prevent them from hauling mainline bypass and non-pri mail. It is my understanding that a Federal Bankruptcy judge said in effect "No way, Jose, Chapter 11 is for companies that are bankrupt, not a loophole to keep a company from losing postal contracts." Following that, Little ACE's lawyers weaseled a 17 day "stay of execution" on some other grounds. I think that will expire sometime next week. Until then, they are still hauling mail. Who knows what will happen after that.
