A friends daughter asked me the following question and now I am intrigued . . . . . If you dropped a slice of bread from a plane at 30,000 feet will it kill somebody if it landed on their head?

No, too much wind resistance the terminal speed would be far too low.
It would also 'tumble' thus lowering the speed even more.
Something like a slice of bread would reach maximum speed after around 10 feet. Dropped from a 1st floor window or from 30,000 ft the final speed would be the same. to get a high terminal velocity you need something streamlined like...

what about a pea from the top of the eiffel tower?
depends if it froze on the way down... otherwise it would just stain your blouse
I guess if you can get a pea that has the same spec. as a slice of bread (the colour wouldn't matter) then it would be OK.
...sorry for the late catch up. Good question about what is spread on the bread as the mass will alter the velocity (but not by much)

Also if the bread was falling 'edge' first it would increase the velocity due to reduced surface area.

Rather than a pea how about a french stick.....that would be interesting to see!

How about a tin of peas Jo, that would make a mess of somone!
It would get eaten by birds before it hit the ground
Didn't " Mythbusters" do something similar with the coin off the Empire State Building. As I remember it was "Busted". It wouldn't kill anyone because of what others have said about terminal velocity.
Lol Rowan - your mum and I must have gone to the same cookery lessons.
