We’re still here, we are still in active development, but we are not ready to make any announcements yet.
We are very interested in producing a product for MSFS. But since our Q2 2021 estimate for the 787 for MSFS was way off. We’ve decided that for now being quiet is better than giving wildly inaccurate delivery estimates.
We hope to be able to announce our development status and plans, but we are not yet ready to do that.
