Dude, just look at Pelosi's flight route in the below, she flied from the east. If Chinese want to accompany her, their jets need to take a big round to avoid Taiwan air space, and after the escort, they need again a another big round to fly back to mainland. Obviously that is too much for a middle weight fighter jet.

How about Americans promised to defend Taiwan. In 1996, 2 US aircraft carriers showed up when Chinese did military drills. Now Chinese again declare their drills which are much closer to Taiwan than any historic crisis, their aircraft carrier was gone? Just look at the below map, you will see how laughable your argument is:

What happened to inflight refueling ?? China got no tankers ??

it's clear that Chinese cucks had no intention or will power to intercept.
Otherwise Chingchong could've sent J20 to dominate 4+ gen fleet that USA sent.

ISRO gears up for 1st runway landing of India-made space shuttle
ISRO is all set for the first runway landing experiment (RLV-LEX) of the Reusable Launch Vehicle - Technology Demonstrator (RLV-TD).
ISRO is all set for the first runway landing experiment (RLV-LEX) of the Reusable Launch Vehicle - Technology Demonstrator (RLV-TD).
ISRO officials informed that the RLV wing body will be transported by helicopter to an altitude of three to five kilometres before being released at a distance of about four to five kilometres in front of the runway with a horizontal velocity.​
The Indian Space Research Organization (ISRO) is all set for the first runway landing experiment (RLV-LEX) of the Reusable Launch Vehicle - Technology Demonstrator (RLV-TD), with its chairman S. Somanath indicating that the weather is being monitored.
"We are looking at the climate. Climate is still not good. So, we are waiting for the wind and other systems to become begin. We will do that," Somanath, also Secretary in the Department of Space, told PTI.
The RLV wing body will be transported by helicopter to an altitude of three to five kilometres before being released at a distance of about four to five kilometres in front of the runway with a horizontal velocity, according to ISRO officials.
The RLV will glide after being released, navigate to the runway, and land independently with landing gear at the defence airfield close to Chitradurga.
According to earlier reports, new systems like landing gear, parachute, hook beam assembly, radar altimeter, and pseudolite have been developed and certified. The national space agency is based here.
On 23 May, 2016, ISRO successfully completed its first RLV-TD HEX-01 (Hypersonic Flight Experiment-01) mission from SDSC SHAR, demonstrating the essential technologies for the design and flight testing of re-entry vehicles.
However, it was a suborbital flight and designed to land on sea. One of the critical technologies to be demonstrated in the RLV-LEX mission is approach and autonomous landing on a runway, according to ISRO.
According to ISRO officials, this milestone (RLV-LEX) needs to be accomplished before the RLV ORE (Orbital Re-Entry Experiment) mission in order to acquire end-to-end reusable launch vehicle (RLV) technology capability. In ORE, a wing body known as the Orbital Re-entry Vehicle (ORV) will be launched into orbit by an ascent vehicle made of the current GSLV and PSLV stages, remain in orbit for a predetermined amount of time, re-enter the atmosphere, and land on a runway without human assistance.
Earlier, Anil Bhardwaj, the director of the Physical Research Laboratory in Ahmedabad, said during a presentation on ISRO's upcoming missions at the Akash Tattva conference that the space agency also intended to send a probe to Mars.

ISRO is on steroids today, enough space copium for this month

Throttlable VIKAS engine tested for ADMIRE booster recovery experiments
I a bit concerned that Vikas is being used in vertical landing test.. The vikas uses hypergolic fuels.. which are very poisonous.. We can expect some crashes.. Unlike the kerlox and methalox , the UDMH as well as N2O4 are poisonous.

Those safety and containment procedures will have to be created then, if they want to keep working on Vikas.🤷‍♂️

Not sure what kind of containment feature is possible . Say the testbed drifts outside the landing zone and they self destruct it now you got a large area showered with a hazardous chemicals.

The Other Engines are in various stages of development. Should be good that ISRO is working in parallel using existing technologies to develop test & validate control laws and algorithms. Once Methalox and Semi Cryo Engines come online - They shall be using those for bigger heavier reusable rockets. ADMIRE is more of proof of concept. Also If Vikas engines shall be poisonous on ADMIRE, then they are already poisonous on PSLV and GSLV series.

On a side note Just like PSLV, GSLV, - ADMIRE Tests shall be carried in remote much akin to SpaceX and Blue Origin.

Actually the ce 200 is a good candidate for vertical landing tests. They would have a far fewer safety headaches with that one.
