That's actually a PSed photo meant as an illustration – as admitted by the Weibo poster – because apparently no photographers were allowed for this launch.
That's a model T. LM-2F is divided into Model Y (for manned space program) and Model T, which is designed to carry space stations and other heavier satellites.

They should focus on using the Hainan base for more of the space launches. The ones in central China are dangerously close to villages and other population centers.
It is not that simple. Haina's advantage is to launch to southeast over the sea. In most cases the first stage won't fall on Philippines. It is also advantages if the intended orbit has low inclination.

When launching SSO and high inclination orbit, Hainan doesn't have much advantage because the first stage will either travel over Chinese mainland or over south-east Asian countries. It is even worse than inland launching. Because from inland site, the first stage would likely land somewhere in China, from Hainan it would likely drop on foreign countries, a bigger trouble.

The first stage landing area used to be no-man's land deep in forest and mountains. It should have NOT been allowed for residential purpose, after all only the state owns land in China, any such expansion of residential land was approved by local government without considering the space agency's need. It is just like how Chengdu city's residential complex has extended at the wall of CAC. There was a decree from central government few years ago demanding local government must coordinate with military to secure military usage of land. This should be applicable to space industry as well.

The design is matured now, note the similarity to X-37 and SR-72

Both will feature State of the art combined cycle engine, interesting enough China already has an article that passed ground tests.
Some clarification.
The Chinese space plane system has two stages
  • The 1st stage use combined cycle engine. This is similar to SR-72.
  • The 2nd stage is rocket propelled by rocket engine. This is similar to X-37.
An analogue is that put X-37 on the back of a much larger SR-72, then you got what China is doing.
Not has would have. Assuming it’s built. As is the space plane was launched off a conventional rocket like X37B. The mother bird doesn’t exist yet same for SR72. This said SR72 as a concept isn’t the same. 72 was meant for military service on its own. The booster shown would be closer to Skylon.

It will be built simply because like the STS it's primarily a PLA driven program and the most difficult hurdles have already been overcome (Materials engineering, Communications, Combined cycle engine) besides the maiden flight is set for 2025, I would say they are ahead of schedule and since it's the Chinese probably under budget too

Why they say the booster crashed near school?

Please, Log in or Register to view URLs content!

Because it did. When a 4B launch happens from Taiyuan, villages and other areas affected by probable stage debris are evacuated. Unfortunately, CZ-8 that uses non-toxic propellant and is assumed by many to replace the 4B series is not ready yet (I think the maiden flight is still planned for this year). So launching from that spaceport while using hydrazine based hypergolics carries a distinct contamination hazard for the specific areas affected.

Is this what China is going for
That's an interesting concept, China actually has multiple programs on TBCC exploring all the options available, The TREE ( rocket augmented) by Power Machinery research institute in Beijing and the TBCC by Chenegdu aircraft research institute are known to public but it's a given that there are more programs under wraps so yeah it's difficult to tell

Dam, I did not realize that this NASASpaceFlight.com site has nothing to do with NASA which I trust would not do such thing as PS.

This was explicitly listed as an illustration, not as a real photo article though. NASASpaceFlight is the premier internet location for anyone interested in Spaceflight. No, it does not have any relation to NASA, although there are a lot of industry and spaceflight experts writing in the site that work or used to work in/with NASA.

It is to Space News what SinoDefence is to PLA watching (but the L2 section in that site is the equivalent of all the chinese speaking military forums combined, as far as primary source attribution is concerned). ;)
