Narrative:

I flew an 8 passenger hab on wed afternoon with passengers. We took of from folley park in chandler, az, and landed sse approximately 8 mi. An uneventful flight. On fri I received a phone call and someone claimed that we startled a horse and an 11 yr old boy fell off and broke his arm. We had no idea that anything had happened. In the area where this supposedly happened, we were 1000-1500 AGL. In my opinion there is no way that I could have caused this to happen. I have never had a problem like this in all the flying that I have done. We fly in the chandler area almost daily along with other balloons. At the time there was one other balloon flying.
