Show and Tell: Navy SPH-3 Flight Helmet

For this week's Show and Tell, Adam shares the latest addition to his helmet collection: an SPH-3 flight helmet. It belonged to Tested viewer David Wratchford, who wore it as a rescue swimmer for the Navy in the 1980s while serving with the "Eightballers" helo squadron. Thanks, David!
