Ok, I will throw my hat in the ring. The trick to the problem, I believe, is
You wouldn't expect this much acceleration because of the effect of atmospheric drag.
The drop took place where drag is the least, at the top of one of the highest Himalayan peaks. The reduced drag more than makes up for the increased distance from the center of the Earth.
The bear was unhurt because,
it fell into the snow covering the mountain top.
So the colour of the bear
is really undetermined since, if you're going to load a bear into an aircraft that is basically a rocket and fly it up over the Himalayan mountains, you can pick any bear you want. However, I will say it was black and white since panda bears are indigenous to the area and because I happen to like panda bears and, yes, I know they are not true bears and that there are brown bears indigenous to the same area but I don't care. Black and white is my answer and I'm sticking to it.
