Richard Hammond reveals the ingenious engineering required to transport one of the most potentially hazardous cargoes in the world in some of the biggest vessels afloat.

Shipping this potentially volatile cargo required engineering solutions inspired by cutlery, mid-air refuelling and fire engines.
