I don't usually give long opinions on these things, but since I'm from Maine too, I will in this case.
I think the salvage company should have contacted the family before looking at legal issues or getting involved in a fight with either goverment.   As a couple of you have pointed out, has anyone even contacted the families involved?  Since they know their names, it shouldn't be too hard to find any surviving family.  
If I were the salvage company, I would have approached the family first so that I had their wishes weighing in on my side in court.  Plus it would just look a little less...well...moneygrubbing is the word that comes to mind.  All sites of this nature should be handled in a respectful way, especially where more than one government is involved.  I wonder if the outcome would have been the same if a 'nonprofit' war memorial committee or museum had wanted to raise the planes and pilots instead of a 'for profit' company.
Also there's this 'war grave' concept.  To me, it would be more inspiring to see the planes these guys flew in a museum and learn about their stories, maybe some of their lives, as opposed to just leaving it alone and letting them and their contributions be forgotten.  At least that's how I would feel if they were my relatives.  
In my opinion, the family wishes of the deceased pilots comes first, then the planes. 
LePaul, Mjolnir is from originally Standish, about 5 miles from Sabego Lake.  I'm originally from Ellsworth, just down the road from you.  We meant to write you ages ago, (we had a maine question for you) but never got a chance to.
