On January 4, 2009, a dual-engine Sikorsky S-76C helicopter crashed into marshy terrain near Morgan City, Louisiana, about seven minutes after takeoff from Amelie, Louisiana. The copter was on a charter flight to a Gulf of Mexico oil rig. Both pilots were killed, along with six of the seven passengers, according to the NTSB.
Heard on the helicopter's cockpit voice recorder was a "loud bang, followed by sounds consistent with rushing wind and a power reduction on both engines," according to the statement. "The aircraft crashed several seconds later."
Feathers and other debris, identified as belonging to a red-tailed hawk, were collected from the helicopter's canopy and windshield, the NTSB said.

So why aren't windows typically polycarbonate? A few layers of that can stop bullets.
- thrownaway2424 11y agoNo idea. You might as well ask why general aviation is still using leaded gas. General aviation is a bit of a shitshow.
- mirimir 11y agoIt's my understanding that high-performance engines require less maintenance running on leaded gas. Or at least, using leaded gas is less expensive than using materials that don't need the lead. So maybe it's just that acrylic costs enough less than polycarbonate to make up for insurance payouts.
