Every now and again, Steve doesn't worry about the price of a thing - no, really! Take this sword that he thought was from Gettysburg. He bought it for about $130, and though a Civil War expert tells him it's definitely from that war, he can't say for sure that it was from Gettysburg. Moreover, it's a musician's sword, so it's not what Steve thought. But no matter the provenance, Steve gets a dark vibe from the piece, and is glad he scooped it up.
Not so with Stef's recent acquisition, which she says is a piece of the Hindenburg, that ill-fated zeppelin that crashed in 1937, killing 36 people. She bought it online for just a couple hundred dollars, which makes Steve highly suspect. Plus, the provenance letter (the document that tells the history of the piece) has an error in it, saying the crash date was in April of 1937, rather than May. But he doesn't have time to worry about it now - he has to prepare for a nerve-wracking escape where he'll dodge a bed of nails swinging at him with the force of a 150-pound dumbbell.
He sweeps himself out of the way just in time, but the stunt cost him a ton of energy, so he's hoping for some good news when he and Stef visit the forensics guys at the University of Toronto. Doug Perovic, the head of the Science and Engineering department, instructs Steve to cut a piece of for review. They find that it's steel, and handled fluids or gasses (right in line with the profile of the Hindenburg), and was deformed in a fire (also a Hindenburg hint).
Steve's last escape really left him fatigued, so he sends Stef and Rob to New Jersey to the crash site of the Hindenburg to see what the experts there have to say. As Carl, the president of the Navy Lakehurst Historical Society, walks them across the field, they can imagine this massive vessel holding so many lives and so much promise clattering to the ground in flames and smoke - a truly chilling image.
They meet with Rick Zitarosa, an expert on this zeppelin, who says that it's very strange that someone would've saved what was probably a pipe from the inner structure of the vessel. Still, as he looks at the letter of provenance, he sees that it contains many obscure facts that are all correct. He agrees with Stephanie that the date was probably a typo, and though he can't say definitively that it came from the Hindenburg, he has no reason to think it did not. Stef calls Steve with the good news, and he gives her the pat on the back she deserves.
Steve gets a close call on one of his death defying escapes.
Steve takes the axe to get it tested for authenticity.
