What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
privacy data omitted(A-320) and privacy data omitted(B-777) were nose to nose awaiting clearance onto RWY31L at taxiway bravo and ke. When privacy data omitted was cleared onto the runway, they powered up to make the 90 deg turn onto taxiway ke and another 90 deg turn onto rwy 31L. Due to their close proximity, debris was thrown onto privacy data omitted with enough force to damage their windscreen. Neither construction debris nor taxiway condition were the source of the debris.
