Better Re-Check Those Numbers

Here is 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.

A huge collection of my 'Factoids' can be accessed from my 'Kirt's Cogitations' table of contents.

Topical Smorgasbord, another manifestation of Factoids, are be found on these pages:

All pertain to topics that are related to the general engineering and science theme of RF Cafe.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
