Big if true. Any volunteers for target practice?

Explanation: During Mehmed the Conqueror’s Siege of Constantinople, he managed to bring down the ancient and formidable city by using a large number of a then-cutting-edge technology - cannons!

They are, indeed, lethal.

Im more curious as to what the community notes was in response to. Like was somebody handwaving the use of cannons?

Bombs aren’t lethal.

Out of most bombs that have been dropped in history, how many have directly hit a person?

Good thing both cannons and bombs are famous for only being effective if they directly hit a person.
