No speed restriction on climbout in Europe or other areas outside the U.S. seems nice, but in some areas, especially Houston, I wouldn't accept it due to the fact it is on a major migratory bird route. Since we weren't given any guidance by ATC,FAA or my company on the seasonal bird patterns, I'd take a vector off course and let the guy behind me do a Boeing windshield test.
Until there is more guidance and research on the subject, I'll pass on the warp speed climb.
My company had a B767-300ER out of CDG going through a flock of something at around 12,000. They were most likely 340 kts +, bird parts penetrated the cockpit and various wing and engine points. No injuries, safe landing. From the pictures of the aircraft nose area, it looked like a FW-190 made a head on pass with the cannons.
