A 50,000 pound utility truck was swallowed by a massive sinkhole in a Florida backyard on Thursday.

The hole, which is 30-feet deep, opened up during an attempt to dig a well in Keith Mannion's backyard in Citrus County. 

WTVT reported: 

"I wasn't quite expecting what I came home to," he explained. "I don't believe what I am seeing."

The owners of other well drilling companies came to see what went wrong.  Craig Newton suspected there was a spot underground that didn't have a clay base to support sand that moves during drilling. "It's just something that happens, it's nobody's fault when that happens."

Crews are hoping to pull the truck out with a crane.

"This is the thing you see on TV and never expect to happen to you," Mannion added. "Well, it happened to me."

Mannion said that he's lived in the home for 19-years and has never had any problems with unstable ground until now.
