There’s a reason why they are not informing us: there’s nothing to say at this moment. Microsoft already said helicopters will come but that it will take time and when they start working on the feature, they will contact the community (especially the HeliSimmer.com community) to help them out.
They told me that personally back in September and they confirmed it during my contacts with them.
Let’s be patient. They have a lot of stuff to do before getting to these complex machines.
