Eli5 Why do people leave doors open in helicopters?

Question

I don’t even like having my car windows open past 40 mph, but helicopters go way faster. Isn’t that an assault on the senses (ears, eyes especially)?

Answer 1

Also consider that many helicopters are used by police, EMS, military or SAR operations, so having the doors open may be a necessity depending on what they’re doing. (for example: you certainly can’t attach and lower a hoist with the door closed)
