How many Blackburn Blackburns could a Blackburn Blackburn burn?
Short answerIts own guns could start fires, but calling in capital-ship gunfire as a spotting aircraft offers much greater destructive power.
NotesThe tongue-twister question starts with the Blackburn Blackburn's own guns and the vulnerability of other aircraft to fire. Its spotting role offers a more destructive possibility: directing naval gunfire onto a concentration of aircraft. That brings capital-ship shells into the hypothetical. The guns mentioned for the period are 13.5-inch and 15-inch weapons.
