Very nice post Sammi and I too salute your Granddad.
My Uncle was a navigator in bomber commend he also didn't say much to me about the war, until I asked him how ha got the burns on his arms. He then told me that his plane was hit by tracer from a ****e-Wulf 190 fighter on the return trip from a raid on Berlin in 1943 and he said he burned his hands dying the fire out which stared near the radio compartment he said that was trying to save the radio operator who was badly injured in the attack. My Dad then later told me that was awarded the DFC for his act of bravery in saving the radio operator.
He was then put on light duties right up to the Nuremberg war crime trials where he was a chauffeur for one of Generals who was in charge (I can not recall the generals name)
Sadly my Uncle died in 2001
