Margaret, I'm so sorry for your loss. Fred would probably have been the first to say he'd had a good innings and ,no doubt, quietly chuckled at the irony of the illness to which he succumbed.
The world of PPrune will be emptier and quieter without him.
i am so pleased he saw fit to share so much with us here. So many war-veterans kept a stiff upper lip to the end and their knowledge and memories died with them. -my own father was in the Merchant Navy in WW1 and was .apparently blind as a result of that service. I never could get anything much out of him. so the reminiscences of the contributors like Fred, become all the more important.
It's marvellous you have the prescence of mind to think carefully before clearing-out.having dealt with 2 deaths recently, I shovelled everything into plastic crates and stored until the family can objectively evaluate.
Once discarded, it's usually gone forever.
Good wishes, I.m sure your Dad would be pleased that you logged-in to let us know he'd departed for blue skies.
