Pioneers don't always get the best land. Some of them end up in ditches
with arrows in their back.
"Engineers from both Boeing and Douglas are reported to have told de
Havilland privately that they also had no idea about the fatigue and
pressurization problems, and may well have made the same mistake if it

had planned for drilled rivets. Wherever the blame is laid, the aviation

about pressurization and metal fatigue"
