I hear, I think the First Officer was female, and the PF ("Pilot Flying"). Based on the "Position and hold" response. Subsequent communication is a male voice, likely the Captain. It is commonplace for the F/O to acknowledge ATC clearance to take the runway (the phrase now, since a few years ago, has been revised to "
Line Up And Wait", this to be more in-line with world-wide standard terminology). After the F/O acknowledges, control for the takeoff is handed over, by the Captain, to the other pilot. And then the PNF ('Pilot Not Flying') handles ATC communication on the radios. I know this is a bit of detail, but I thought I would add it, nevertheless.
(You can hear a 'Master Caution' audible alert in the ATC recording, as the pilot had his mic open and transmitting. {Three rapid beeps}.)
COA 009, KEWR - RJAA (Newark New Jersey to TOKYO, Japan!!} A very, very long flight, with a LOT of fuel at Dispatch...and COA 009 experienced a HYDRAULIC problem (full system leak for the affected system) when the Landing Gear were selected to "UP".
Required a "RTD" or "Return to Departure" and thus, a fuel dump as part of the Emergency Procedure to comply with maximum landing weight AirFrame restrictions..
