Family of balloon boy featured on 'Wife Swap'

Authorities were still searching Thursday for Falcon, the son of Richard and Mayumi Heene of Fort Collins, Colo. Falcon's family was last on "Wife Swap" in March, favorites of the audience who had voted to have them featured again on the show's 100th episode.

In "Wife Swap," two mothers trade places for a few weeks. Producers try to match families with wildly different attitudes and lifestyles to see if sparks fly.

When they first appeared last fall, the Heenes were described as storm chasers who lived on the edge and were matched with a Connecticut family who considered safety to be paramount.
