Yes, all three of those instances involved a Quinjet. I'm not sure what page you're looking at, but all three of those instances, though not stated in quite the same way, are definitely part the history section on the Quinjet page.

Keep in mind that the article we have titled "Transport Plane" is referring to a specific model of aircraft, namely the one that has just recently begun appearing regularly in Agents of S.H.I.E.L.D.. Don't get caught up in the name either, as this is a temporary name given to that particular model of aircraft by a user at this site as a simple, specific way for us to keep up with the information/history of that aircraft until an official name is possibly given in the future.

Also the Quinjet in that quote/example is being referred to as "transport" because its function is to transport things, like any vehicle. It was supposedly transporting personnel and supplies, so air traffic control would refer to it based on that, not by name or title.
