Americans know that the U.S. government and defense industry exports huge amounts of military goods to Israel — but they may not be aware that in some cases these shipments travel beside them.

On Saturday afternoon, a cargo airplane carrying 14 tons of explosive materials bound for an Israeli weapons manufacturing company is expected to fly out of John F. Kennedy International Airport in New York on Saturday afternoon, according to air cargo documents reviewed by The Intercept.

The explosive material, grade A nitrocellulose, is a widely used industrial material that plays a key role in making ammunition — from sniper bullets to rockets.

The cargo flight by Challenge Airlines Israel is scheduled to depart from JFK at 2 p.m. on Saturday and land in Ben Gurion Airport in Tel Aviv on Sunday
