I am currently reading: 2nd Tactical Airforce by Christopher F. Shores. On page 41, when discussing the Hawker Typhoon, it has the following to say:
I was wondering if there is any evidence for this claim, any pictures or eye witnesses or is it a case of a pilot saying he did it i his memoirs?an experienced pilot, providing all four cannons were operating, could literally write his name on the ground with cannon fire.

Mark.
