From the report:
> The MP initiated a conference call with Lockheed Martin engineers through the on-duty supervisor of flying (SOF)
"MP" is the pilot
> A conference hotel is a call that can be initiated by the SOF to speak directly with Lockheed Martin
engineers to discuss an abnormality/malfunction not addressed in the PCL (Tab V-13.1, 14.1, 15.1,
16.1, 17.1). While waiting for the conference hotel to convene, the MP initiated a series of “sturns” with gravitational forces up to 2.5Gs, as well as a slip maneuver (i.e., left stick input with
full right rudder pedal) to see if the nose wheel orientation would change (Tabs N-12, BB-201-
02). Upon visual inspection, the MW reported no change to the nose wheel (Tab N-13).
The SOF informed the MP he was on the phone with the conference hotel and Lockheed Martin
were getting the LG subject matter experts (SME)
So the pilot was, in effect, on the call, even if not directly on the phone. I don't know for sure, but I'm guessing an F-35 pilot had radio comms with the SOF who was on a phone line. It's a layer of indirection, but the pilot was essentially exchanging info in real time with the conference call. Its not a stretch to colloquially say that the pilot was "in the conference call"
