This is the tour company that we used. Here, the ground staff is removing the doors. You have the option for flying with doors "on" or "off". By all means, fly with them off! Yes, you will be buffeted by the wind and it will be noisier. Yes, it will be cooler too. But it is much more exhilarating and better to take pictures with the doors off.

You are provided with headphones to talk to the pilot and other passengers.
