I think it was Henry Morgan. Halfway across the Pond in the middle of the night I got out of my seat to go for a walk (we are in a Belfast). Going past Henry I asked him in a jocular fashion "Are we lost then Henry". "No" said he. "Are we on track then Henry". "No" said he". "Well, if we are not on track and we are not lost, then where are we?". "Well, we are not on track but No.3 engine is!!".
