Better Re-Check Those Numbers
a lesson in how placing total faith in computer simulations can be utter
folly - and deadly! As part of NASA's investigation into the shuttle
Columbia's breakup over TX last winter, Boeing, builder of the wing
leading edge (LE) sections, presented simulations
proving that the dislodged chunk of main
fuel tank insulating foam that struck the LE could not possibly have
compromised the structure and therefore precipitate the disaster. Later,
NASA engineers fired a similarly-sized real chunk of foam at a real
wing LE, and were shocked to witness the resulting 16" hole! Boeing's
detailed report, complete with tables, graphs and charts from their
simulations, insists the hole isn't really there.
