Flight Crew Human Performance
En route at FL400; the left side outer windshield shattered. Immediately we contacted center for descent and was cleared down to 11000 ft. We landed at the closest major airport which was chattanooga; tn. I contacted dispatch to alert them and to start making arrangements for another aircraft to take passenger to their final destination. I contacted chief pilot and was told to contact fleet manager and our company director of maintenance. While talking with fleet manager; I explained the situation and damage of the windshield. I was told that if there was no change in pressurization at time of crack then the 2 inner panels did not break -- only the outer; and the aircraft is capable of flying safely and that they have seen other excels fly with cracked windshield. In discussing this with fleet manager; and VFR conditions between the 35 min flight; I elected to fly the aircraft on to the fleet center at 11000 ft and for safety not to exceed 250 KTS. I failed to contact our company director of maintenance which would have told me I needed a ferry permit.
