BlazerLT, may I ask what your experience is, and what your day job is? You may think it is irrelevant, but it is not.
You suggesting that you being a trained and certified fluid power and pneumatic technologist also means you have more experience on this subject?
I take it that you have more experience and time with this type of data and information than this person, who works in the field?
A little hard to dismiss one's knowledge who works with this type of data and information, on what seems to be a regular basis, right?
By the way, knowing a few Ford and GM engineers in the past, I've seen this. People who do not have as much experience and time on the subject as the engineer, still question the engineer's knowledge, nevermind the fact that the engineer is exposed to the data and information on a regular basis and has more experience and time than anyone in the public. By the way, BlazerLT, I'm talking in general, not you specifically. The link provided shows people who agree and disagree for various reasons.
I'm not saying engineers are Gods, neither are us, but the ones that I know, aren't your average guy. I guess it's human nature for us to try to make everyone on the same level. I'm sure people would like to think that they have more knowledge than an engineer in a large corporation who works in the field with such information on a regular basis. Just human nature.
