Not a great piece but a good summary. I like the chart at the bottom of the 2nd page showing clearly (something I kept repeating) that nearly everybody  tried during the last 20y to build a new Mirage 2000... Except Dassault.

Most people going from a to b are just going from a to b.  Not going out with the intention of finding/spotting unusual UFO.  Why would I for example EXPECT to see specialised or secret new/black project aircraft and is it really worth taking high def camera equipment everywhere I go just hoping?  Most of us have better things to do with the time between B and D.

Hi,

also I suggest that we can make a seperate section for actually built aircraft,instead off put
it in Aerospace section,and it will be only one section from the year 1900 up to 2019 and
more.

Huge benefits of scale which historically, have been completely offset by a lack of cohesion in development.  Nice idea but it needs everyone to leave their ego at the door.

SpaceX gains FRR green light for DM-1 mission to the ISS

Quote
Dragon 2 remains on track for her maiden flight to the International Space Station (ISS) in March following a green light from the key Flight Readiness Review (FRR) on Friday. The Agency Level FRR meeting was the final review stage from all relevant elements involving SpaceX, NASA Commercial Crew and the ISS program, with the milestones now progressing towards a SpaceX Launch Readiness Review (LRR) a few days prior to the March 2 target.

I've been liking this thread, along with all the analysis. But a question keeps coming to mind for me.

Why has it suddenly been revealed ?   ???  I would have thought the Russians would have it wrapped pretty good
It would be known since first flight anyways(which is close). Spotters don't sleep.

The key to getting good pictures of flying aircraft is using an actual camera with a long focal length lens. 

According to an article about 2018 iPhone cameras ( https://qz.com/1395779/the-amazing-sorcery-of-the-iphones-newest-cameras/ ), the actual focal length of its tiny telephoto lens is 6mm but achieves an equivalent focal length of 52mm through advanced hardware and software technology.  52mm is good for taking pictures of things you can walk up to or very large items at a distance. 

My digital SLR with its 300mm telephoto lens takes passable pictures of airliners 25 miles out on approach to DFW and you can see details like windows and control surfaces.  It only gets the airliner’s shape at contrail altitude.  It is a wasted effort to use a phone camera with a focal length far under the several hundred millimeters needed to take useful pictures of flying aircraft.  Serious aircraft photographers use much longer lenses from the ground.

Only real cameras with long focal length telephoto lenses can capture decent pictures of flying aircraft.

Its got too much wing for a low level supersonic design IMHO.

Also too much landing gear. It sure looks like they built it to carry a lot of weight.

Could it be that they just reused an existing landing gear for the prototype for economic reasons, but the production one could be different/lighter?

Be that as it may, but showing one blurry blip of light against a pitch black screen background with a drawn overlap of a supposed object more than two orders of magnitude larger in acreage is almost worse than having no visual evidence at all. I'm open minded, but I'll reserve judgement.
