Me again with a strange request: I'm looking for an image - if my memory is correct - showing several PLAAF soldiers (might have been cadets ?) standing in uniform forming a "70" for the 70th anniversary?
... I can't find it anymore.
Best and thanks

Not sure if this video on a Golden Helmet pilot is a repost.

An interesting research paper on an escape pod for a multi-role high-mach/hypersonic, low-orbital vehicle.
Abstract: The integral escape module concept integrates the seat and the cockpit in order to obtain an independent aerodynamic configuration after ejection. A maximum protection can be offered for the crew from high-speed wind blast. Therefore, the integral escape module will be one of the important approaches for the design of the escape system for the aerospace vehicle. In this study, we first conduct numerical simulation of an integral escape module to evaluate its basic aerodynamic performance. Then a rigid brake parachute scheme is proposed to improve the stability and deceleration efficiency of the integral escape module. Finally, the unsteady computational method with a dynamic chimera grid technique is applied to the simulation of the escape process. The numerical results reveal a lack of static stability of the single integral escape module. However, both static and dynamic stability can be significantly improved by using the brake parachute combination scheme in the wide flight envelop of Ma=0.3~4.0. With the growth of Mach number, the stability increases at subsonic speed, while decreases at supersonic speed. The dynamic stability can be further improved by reducing the flying altitude to increase the dynamic pressure at high Mach numbers (e.g. Ma=4.0). In the wide flight envelope, the ejection escape trajectory of the integral escape module shows that the module combined with the brake parachute can be safely separated from the aerospace vehicle assisted by the ejection force and rocket thrust, with its attitude converging gradually.

Wasnt there something recently about a space helmet shown somewhere? As in, pilots will need to wear this helmet for a new very high altitude plane.An interesting research paper on an escape pod for a multi-role high-mach/hypersonic, low-orbital vehicle.

I feel China still has a need for a supersonic conventional sweep wing high attitude bomber beyond the ceiling of fighter jets and hard for the SAM. Even if they have H20, it should not be used lightly. If it's down at enemy territory for whatever reasons it would be devastating, like the F117 ended due to a jet down at Yugoslavia. H6 is too slow, needs fast bomber that can enter and exit quickly that can outrun fighter jets like TU160. Maybe get a tomcat from Iran for study.
J-16 has entered the chat
- The ability to fly fast and the range to fly deep into enemy territory without escort fighters to fend off opposing air-to-air threats
- 12 external hardpoint pylons to arm a wide variety of bombs (unguided or laser/Beido-guided) and munitions

The US tried that approach with XB-70 back in 1960s. A mach 3.1 intercontinental bomber. They concluded that even by the end of 1960s, meaning against the SAMs and interceptors of 1960s, the whole fly high, fly fast approach was pointless. Trying something like that today would be colossally expensive and suicidal.
