I went to a place where they did that when I was younger. We were visiting a monastery and were told to be respectful because there was a sky burial going on while we were there. We decided to just look around but to keep away from the ceremony. I was really out of it with altitude sickness so I was just sitting looking down at this gorgeous valley near the bus, while the people I was with went to look around the monastery. Then I could see all these vultures flying away with little bits of meat. Very surreal experience.

Some skydivers will have "ash dives." Your body is cremated, ashes placed into a specially designed pouch, and friends take you up on a final skydive. Everyone exits, joins up in a formation with your pouch making up one of the links, and at some point in free fall the pouch gets opened. You're quickly scattered to the ends of the earth from a couple miles up.

Even though there's no cremation involved, Tibetan sky burial sort of reminds me of that.
