Narrator, Dr. Ernhardt [as Narrator] and others in “Cavalcade”

This twisted tornado-wracked pile of stem was a microwave radio relay tower...

Now, it's garbage.

A link in our nation's complex telephone network. Minutes after the tower was felled by a tornado, service was restored by switching calls to alternate routes of the network, but a temporary tower must be erected, and quickly.

Before it kills again.
