Henderson's unannounced inspections let him examine work before a yard's management could arrange a formal visit. In the Ark Royal anecdote, the director at Cammell Laird found him inside a fuel tank assessing the welds. The director knew riveting but had not mastered the welding methods his yard had recently adopted. Henderson reportedly explained the defects, requested a torch, and offered a practical demonstration. The director later defended his knowledge of welds during a visit by Churchill by invoking Henderson's personal instruction.
