Russia's Central Aerohydrodynamic Institute (TsAGI) -- think NASA's Langley Research Centre -- is working on a new supersonic business jet. (See here for Russian-language news release issued earlier today.)
Sukhoi and Tupolev of course have been working on this idea for decades, of course, but this one will be a little different. It's supposed to fly quietly enough that it can operate over populated areas, unlike the supersonic Concorde, for instance. That's all very interesting in a Bond-villain-plot-vehicle-way, but that's not why we're posting on this blog.
We'd really just like to know why TsAGI decided to paint the concept aircraft in drab olive green, the colour of World War II-era camouflage. Maybe the "green" marketing meme has made its way into Russian design offices. Of course, associating the environmental green with anything that flies supersonic is a bit of a stretch.
Russia's Tupolev is working on a next-generation bomber ... just saying.
