Well when we got sued by the company they specifically cited this site and used it against us so yes, yes they do.

A good chunk of 121 pilots all have 91/135 experience including myself. What I learned from that was coloring outside the lines is the reason bizjets keep crashing. The get er done attitude wasn’t welcome in my cockpit and I never saw it at Spirit or my current shop. If Spirit needs planes to land unstable with tailwinds on 4,000’ strips, you’ll be the first one to be called. You have a lot of presumptions of what we do in the 121 world and it’s pretty funny. You’re not the first pilot to think they’re different or special.
