OF COURSE people continue to fly during this. They do not go low over the person searching and watch carefully when he is close in - but they do NOT stop flying.
At the electric field in San Diego where I am a member, there is a bike path a couple of hundred feet out where people go while flyers are in the air. This is no problem and completely customary. Beyond the boat path is Mission Bay (east side) where boaters may be.
This field is on city property and near San Diego International Airport. Civilian and military helicopters are also traversing the area. We must drop down to low altitude while they are going by. This field is under the most rigorous requirements imaginable.
Flying over people with an RC model is no big deal as long as common sense is used. It is completely legal also.
