As you mention Ted Sismore Henry, it is also worth mentioning 'Mickey' Martin who was a 'Dambuster' with 617 Squadron. He also became an expert, with his crew, in accurately dropping Barnes Wallis's Grand Slam and Tallboy bombs. The Bielefeld Viaduct was a classic example. The Saumur Tunnel and the U-Boat pens at Brest were others.
Also, Guy Gibson told many times that MM was the best pilot at low flying he had ever seen.
