[6] Maltby's maternal uncle was the First World War Royal Flying Corps pilot Aubrey Hatfeild MBE.

On 4 May 1942 whilst on a mission to Stuttgart, Maltby and his crew had taken heavy fire shortly after hitting enemy coast.

[9] Maltby made the decision to head back to base at Woodhall Spa but was directed to land at Coningsby instead due to it being a grass runway.

The first three aircraft to attack the dam (Guy Gibson flying in G-George, Hopgood in M-Mother and Harold Brownlow Martin in P-Popsie) all missed the target.

His Lancaster JA981[17] crashed into the North Sea while returning to base after the mission had been cancelled due to fog over the target.

It is probable that the cause of his death was a collision with a 139 Squadron Mosquito aircraft (DZ598) piloted by Flt Lt M W Colledge and navigator Flg Off G L Marshall, who were returning from an operation to Berlin, and was on a course for RAF Wyton, Cambridgeshire.

[7] Dave Shannon, a fellow dambuster, circled the crash site for two hours whilst waiting for rescue.

[21] Several other pieces of memorabilia related to Maltby have appeared in recent years, however many of these have been subject to critique and doubt over their legitimacy.

In November 2019 a teddy bear named "Pinnie The Wooh", said to have flown with Maltby on every flight, was revealed to be going up for auction in Bristol later that month by an unknown seller.

[22] The Maltby family later released a statement that they were unable to provide the authenticity for this item along with others that have been rumoured to be up for sale saying they never knew of their existence, and if they had, then they never would have given it away.

Others have pointed out that the bear is in remarkably good condition considering it was recovered from Maltby's body which was found in the North Sea.

[23] Another piece of memorabilia allegedly passed on to Maltby's father's collection at his school was a pair of marbles that Barnes Wallace used to test his original theory behind the bouncing bomb.
