I recall some controversy a couple years ago over suspicions that defense contractors were using them to train weapons systems. A few people got captchas asking them to identify helicopters.
I'd love to identify helicopters. I do get planes now, but was it specifically military helicopters?
I like getting to identify basic things like cars, airplanes and trains with hCaptcha. It's like a picture book for adults, and feels strangely pleasant compared to other captchas.
