In what Beagle (and I) fondly refer to as the olden days, good but overconfident pilots were usually sent for a first tour on something single seat. At a time when the RAF had hundreds of them and not that expensive, these young men either frightened themseves
less and moved on or killed themselves and hopefully nobody on the ground. Obviously times have changed and close supervision is today's answer, something which seems to have been sadly lacking in the B 52 debacle.
