Vic Armstrong explains it differently in his book. Harrison Ford says it was his idea.

Reminds me of 3 blind men describing an elephant.

None of them has ever been able to say definitively who first suggested it. To be honest, they've all pointed the finger at another. Steven says it was Harrison. Harrison has said it was George. George has said it was Steven. Who the hell knows.
