There are only 10-12 human cannonballs working today and it is a highly secretive trade generally kept within families. How the cannons work are unknown due to the secretive nature. Cannonballers don’t even share how their cannons work with each other.

A circus historian says that only 50 people have attempted the act and 30 of them have died. Another person thinks there have been closer to 100.

Human cannonballers are in the air for less than 3 seconds, but travels more than 60 mph and can hit a g-force of 7. The average person passes out at 5.
