Another Report from the Salt Lake Tribune
Shell misses mountain, lands in neighborhood
No one hurt: Dad says shrapnel just missed his 3-year-old son "by inches"; UDOT takes full responsibility

A 20-pound artillery shell loaded with too much gunpowder overshot its Provo Canyon avalanche target Wednesday by about three miles, exploding in the back yard of a Pleasant Grove couple and piercing three homes with shrapnel.
Remarkably, no one was injured.
Now the Utah Department of Transportation is scrambling to understand what went wrong and make sure it never happens again.
"We took full responsibility for this incident and we're extremely grateful no one was hurt," said Carlos Braceras, deputy director of UDOT.
Around 3 p.m., atop Arrowhead Peak, UDOT fired the 105 mm shell from a howitzer artillery cannon - leased from the U.S. military - toward the Lost Creek slide path area in Provo Canyon about two miles away.
But the shell kept going.
The military sends the shells to UDOT pre-loaded with seven packages of gunpowder. The operators were supposed to remove two. Instead, it was fired fully loaded, and rocketed into the residential neighborhood.
UDOT didn't realize the shell had exploded in Scott Connors' back yard at 1665 E. 480 South - creating a 3-foot-wide crater that was a foot deep - until the 911 calls began to come in.
"There was a big explosion," Connors said. "I saw the window in the family room blow out. Glass covered my son. He started screaming."
Shrapnel barreled through his house, nearly injuring his 3-year-old son. "We felt . . . quite sure that a couple of pieces just missed him by inches," Connors said.
The blast also damaged Connors' shed and sent shrapnel through a fence and into a neighbor's car.
The Pleasant Grove man's first thought was that a propane tank stored in his shed had exploded. He called 911 dispatchers, who instructed him and his family to leave the house. Police and fire personnel determined an explosive had detonated and evacuated nearby homes. A bomb squad was called in.
By about 9 p.m., officials knew it was the errant shell and allowed Connors and his neighbors back into their homes.
While Braceras did not have an estimate of the damage to the homes, he said UDOT will cover the full cost of the homeowners' repairs. A safety risk manager was at the site Wednesday assessing the situation.
"They [UDOT] have told us they're responsible," Connors said.
"I don't need to tell them. They said they're investigating the incident. So, you know, I'm not angry with them or anything else. I believe it was purely an accident."
That said, he added, "We're just glad it wasn't any worse than it was."
On Wednesday, winds gusted between 40 and 50 mph, whipping up snow and blurring visibility. The cannon's operators didn't see where the shell landed, which, according to Braceras, is typical.
In 2001, UDOT began using artillery shells as its primary method of avalanche control since bad weather often prevents helicopters from flying in and dropping 2-pound hand charges.
"What the military weapon allows us to do is provide the greatest level of safety to the motorists," Braceras said.
UDOT reviewed the details of Wednesday night's accident before firing shells in Little Cottonwood Canyon on Thursday morning.
"To say we didn't have the highest awareness of safety beforehand would be false," Braceras said. "But we're actively discussing what happened to make sure that didn't happen [Thursday] morning."
