Also, at some point this has to slide into the realm of fraud to the gov't/consumers. Here is my logic... I assume when a plane has a mechanical, they record and must report it to a gov't agency. Likewise, when there is a missed flight and they do not report a problem to a gov't agency... the stories would not match. Or if UA sends you an email or something else that says there was no problem... then the tell the FAA or some other agency there is a problem... it just seems like fraud somewhere.
