Can somebody answer our question? 

How many are on the road?

Why did it fail?

Why does a bomb squad trailer that comes loose and hit a school bus have to happen and cause an injury and death's before we get our questions answered?

The Youngstown Bomb Squad and the Hubbard Police are on South Main Street next to the Calvary Christian Center and across the street from Walgreens, but there's no cause for alarm; there is no threat.

The Youngstown Bomb Squad commander said the truck was coming back from the car wash when the hitch got loose and the bomb squad trailer separated.

They are working to get it taken care of and should be back on the road within 15 minutes, the commander said.
