What that article says is that XOJet crews don't care who is in back. If the situation warrants diverting to safely get on the ground, we'll do exactly that. Can't fault a crew for making that decision.
What it doesn't say is who was operating the first aircraft that had a mechanical. Could have been an XOJet plane, that did not continue their trip due to maintenance. Or it could have been another operator that had issues and called XOJet to recover.
Regardless, you have 2 crews who took care of their passenger and airplane when the going got tough. That XOJet potentially had 2 mechanicals on the same trip? We have almost 50 airplanes...mechanicals happen. Its happened before, it will happen again.
To answer your question, XOJet is owned by TPG...a company in the same business as Bain Capital. Probably not left-leaning
