is the sky the limit?

Is there a limit to altitude in Second Life?  I don't know. But just for fun I thought I'd test that.
I ended up flying to 100,000 meters.  Yes, that's right - 100,000 meters! That is equal to 62 miles.
When I began my descent I started the stopwatch.  It took approximately 32-1/2 minutes to land; which also included the last 100 meters when my parachute opened and slowed my descent.  My speed of descent would be something like 124 mph.  Okay, I'd call that fast!
