Of course, aircrew moved types more often then, both military and civil. It's quite possible that he flew VC10s and 707s for BOAC.
Come to think of it, ISTR he mentioned VC10s at the dinner - but it was a very good dinner, so my memory may be inaccurate.
He was talking very much as old(er) pilot to old pilot - scarcely a whiff of the politician about him that night ....
