A clear “no”. Helicopters need certain visibility to be allowed to fly. In addition, we do not necessarily fly in any weather that we should be allowed to. The pilot collects a special flight weather report every day of the flight and can decide against a flight at any time for safety reasons. If a flight cannot be carried out due to bad weather or other conditions, the tickets remain valid and a new date is agreed. Light splashes of rain, on the other hand, don't bother us as long as visibility is good overall. A blue sky without a single cloud is quite boring to be honest. Most sightseeing passengers look down and not up anyway.
