Very Sad
I used to operate these aircraft for the company and they are a thrill to fly.
Old airframes, but heavy maintenence daily.
As for the spar, Grumman mandated that the spar for the larger ALBATROSS be replaced after a number of hours, replaced with TITANIUM spar at the cost of a million plus.
Very sad day for aviation indeed, highly probable that the oldest operating airline in the US will be closed for good.
My thoughts and prayers to the crew, passengers and their families.
Let the legend live in memory
