No, actually; the average bullet travels at 2,500 feet per second (around 1,700 mph) [1].
Also, the pilot of a member of the Jets of Norway R/C club. These are probably some of the most experienced r/c jet pilots in the world. I'm sure they understand the risks involved better than any of us in this thread.

- jpitz 12y agoHandguns are far slower than rifles. .45 ACP usually goes about 1000 f/s. That jet, flying at half the speed of a .45 caliber bullet, weighs at least one hundred times as much. I think that's the point GP was trying to make.
- lotsofmangos 12y agoThe kinetic energy goes up by the velocity squared but then any damage done by the impact would be a function of the impulse and the cross sectional area of the impact. I certainly wouldn't like to get hit by this, but it is probably less lethal than those rubber rounds they use in crowd control. edit - Boxer Rocky Marciano's punch was measured at 1028 joules, which is supposedly a greater kinetic energy than an armour piercing bullet. Direct kinetic energy comparisons are not as useful as you might think.
