Two wise, delightful structural engineers explain what can go wrong in their trade.

"You won't have instruments with which to read anything else," the engineer explained.

"I used the radio to wire up the warning," the engineer explained without looking away from the panel.

"As a headquarters for the causeway workers," explained the engineer.

"That is the purpose of the test, to see if it works," the senior engineer explained patiently.

But the engineers still explained more than they ever have before in the news media about how their search system works.

"Everything needs to go in the larger wagon," the engineer explained.

"We took two shots and both were kills," the engineer explained.

"The conductor has left the train to go to the bathroom," the engineer explains.

"I mean, going to the roots, you know," the engineer explained, with an air of enjoyment.
