Kristan,

How often do you strike 4 pounds of bird? Other than ducks and geese, I
can't think of many 4 pound birds you might run a plane into.

Suggest you see:

https://www.avemco.com/briefingroom/birdstrikes.asp
http://www.aphis.usda.gov/ws/nwrc/fi...ky/strike.html

and many other good sources that I found with a Google search (terms: "bird
strikes" +"aviation").

In years past, there were certain seasons when one flew certain military
low-level training routes with extra caution due to bird strike potential.
Low-level hops in areas where 20 lb.-plus carrion birds are common
(Southeastern US, for instance) can be particularly hazardous.

BTW, low frequency is irrelevant if it happens to YOU.

I'm guessing the myth in qustion is about the frozen vs non-frozen
chickens.* It will be interesting to see what the Mythbusters

it.

Watched the program.
Their conclusion, frozen or thawed makes no difference to impact.
Strictly a function of mass, velocity, and time of deceleration.


Hmmm, I suspect when dealing with a kg of water it makes a
big difference to the fan blades if that water is frozen
in a single lump.

Maybe in the case of water. But I once talked to an engineer involved
in developing the canopy for the Shorts Tucano and he basically said
the same thing - frozen chicken, thawed chicken, made no difference to
the damage caused.

IIRC he said it was a 4lb chicken that was used as standard.
