First, DC-9, not -10.
I think that decision was made based on the assumption that no one was shipping pax oxy generators in unauthorized, unlabelled containers illegally. Given the rapid propagation of that particular fire event, it's doubtful even the "fix" would have prevented it.
Oxy generators are, under the wrong conditions, "somewhat" more active than lithium batteries which have reached thermal runaway.
Wing flutter was recognized during test flights, and an initial fix - through software - was put into place. This appears to be a follow-up to make sure that all operators are compliant.
Curious. I seem to recall the the original prototype 747s had a flutter problem too but it was fixed before production.
Yes, I recall that as well... Well, not really recall it, but feel sure that I've read it some where.
Cheers!
