Pathfinder crews consisted of members who had flown a minimum of 45 operational sorties and while they were the best, they were made from all ranks and backgrounds.
The Master Bomber was the aircraft in charge of the whole attack. They would transmit instructions over VHF radio to the main force telling them what colored markers to ignore and what to bomb.
