Hi Martin,
Very interesting photos, thank you for sharing with us all! I trust your grandfather survived this incident! I was wondering if you would like to add your grandfathers story on our remembrance website? We would be honoured to make a page for him. I note that you are in MK, I live in Rushden near Wellingborough, Northants. Please send me a PM if you are interested, I can then give you my e-mail address.
Thanks again,
Melvin
