"I saw a program about that and they mentioned that a large part of the

their procedures for the conditions under which the bonding took place
after those early planes were made and Aloha hadn't been carrying out
the checks properly to detect telltales signs of the problem.

Its something I consider when I see people querying about bonding car
panels and what conditions they are done under. Temperature, humidity,
surface prep can have a critical effect. "

Considering Boeing is now building planes that are made of carbon fiber
and LOTS of adhesive, it will be interesting to see what their long
time life span (and maintainance costs) will be.
