I just came across this in the War Diary of the 9th Heavy Battery, RCA. The battery was manning two breach-loading 8-inch Mk VII-A howitzers in East Lawrencetown, Nova Scotia on July 23rd, 1941 at Lloy Station on Porter's Lake. It looks like a pilot from the 118th Fighter Squadron, RCAF based at Dartmouth, Nova Scotia went a little too far with his plane. See the account for the day in the War Diary entry.
If you use Google maps you can find the indications of the Battery's position that still exist today. Here is a map of the position from 1940.
It is amazing how many pilots were killed in training and/or non-combat operations. My wife's uncle was killed in 1943 during a botched landing.
Look what happened four days, on July 29th, at the same Battery. It is amazing that this squadron was the only fighter defence in Eastern Canada at the time!
Ultimately there were 37 home based squadrons in the RCAF with another 48 overseas. In 1941, most were already in Europe. .
