Aircraft
Enroute at cruise; FL360; felt and heard a thump on the left side of the aircraft. Immediately noticed that the L1 window was cracked and spider webbed from the lower left corner; 2/3 of the way across. Pulled out the QRH and went through the Window Damage checklist. No inner damage or air leak was detected; so the decision was made to continue to our destination. Descent and landing were normal; with the First Officer making the landing.
Cruise flight at FL360; we heard a loud thump. Looking up; the Captains #1 window had a large spider web of cracks across the outer pane. We ran the QRC procedure; selecting the window heat to off; [and] noted there was no change in airflow or cabin pressure. We elected to continue to destination and not declare an emergency at that time. No weather or turbulence was noticed in connection to the window's cracking before or after the event. On landing there was a baseball sized cluster of cracking in the lower left corner of the window.
B757-200 flight crew reported Captain's windshield outer pane failed at FL360 since the inner pane was undamaged; the flight continued to destination.
