Flight Sim Labs, also known as FSLabs, is a well-known aircraft developer standing behind the Airbus series for Prepar3D. Today, the developer has come to their Facebook page to share a single screenshot of the legendary supersonic aircraft, Concorde, in most likely Prepar3D.
It is unclear if the aircraft will be compatible with Prepar3D v4 and v5 or the new Microsoft Flight Simulator. On the screenshots below, we can see that the aircraft exterior in very dark conditions. Due to that, we have brightened the image a bit.
The screenshots are most-probably from Prepar3D v5 due to the PBR materials and textures equipped, however, this is not confirmed information and just our opinion.
FSLabs had their Concorde rendition already released for Prepar3D v3 and FSX in the past, but stopped selling it. The official support of that aircraft ended this June.
