VFRPilotpb, milspec in reality means little. The windshield in a B206 is identical to that in the OH58, or at least the original models. And it's not even close to birdproof. I've seen several that were shattered by seagulls and smaller species. I've hit lots of birds, including at least half a dozen seagulls, but fortunately none of them in the windows. I have disintegrated them with the main rotor, partially disabled them, and had one come down through the main rotor blades at idle completely untouched. One of the scarier bird sightings happened at about 2AM on a very dark night. A goose came by, missing the left windshield by about 2 feet. Fortunately, I was in the right seat at the time. ;-) That goose would have caused lots of damage, and possibly killed anyone behind the windshield that it hit. Where it was going at that time of night I have no idea, but I don't ever want to see it again.
