Witnesses said it appeared to break in the middle and the front half exploded, the tail end fell in the Humber River, Hull, England, there were 4 survivors pulled from it. One being the pilot.

Cause of Explosion: Zepplins fly on hydrogen and as a result of their highly flammable lifting gas, it exploded over the river with thousands of spectators on the shore watching this amazing aircraft take off. No one on the shore-side were injured.

LT Esterly is now buried in the Lake Park Cemetery, Youngstown, Mahoning County, Ohio, USA.
