What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
All preflight operations were normal, and all checklists were completed without issue. Weather conditions included a storm system approaching the airport from the south, with winds increasing from that direction and gusts reaching up to 44 knots.
Taxi to the departure runway (runway 21) was uneventful. Upon receiving takeoff clearance, aircraft taxied onto the runway and aligned with the centerline. Before advancing the throttles for takeoff, both front windscreens suddenly cracked and spiderwebbed across the entire surface.
Crew immediately informed the tower and requested to taxi back to the gate. The return taxi and arrival at the gate were completed without incident. All passengers and crew deplaned normally, and maintenance was notified for further evaluation of the aircraft.
