yes they canThey fly in very intricate paths.
About 3 miles up.
Not on their own, but bees have been taken up into space to see how they build comb in a no-gravity situation.
Bees can fly up to 55,000 meters in a two week period. If the ocean is on low tide, they generally do fly over. Eventually dying several miles at sea.

If you find a bee that seems unable to fly it may be cold -- they need a body temperature of over about 70 degrees F or they cannot fly -- or it is possible the bee is at the end of its life. Honey bees in particular will fly until their wings get too tattered for them to fly any further, then they will die.
Turkeys don't fly a lot. They can fly short distances, and they fly down and up from their roosting trees, but they do fly.
