Re: MiG-21 Bison shoots down F-16 in Kashmir

lalmo no ji for me.
what protected AV from the blast near the tail could be the design of mig 21 cockpit. The pilot sits well inside and the canopy barely rises above the spine. But this also hampers rear view visibility. All efforts in design were focussed on supersonic performance.

Could be a flat spin. The way the Mig hit the ground it appears as if port side wing hit the ground first then the fuselage. The wing is totally mangled, twisted over the fuselage. The starboard wing OTOH is distinctly identifiable and other parts inside fuselage.

Singha,
For A330 awacs, that is only alternative to IL 76 to mount CABS radome. Boeing wont spare its 737 airframe since it already has a product based on same airframe. Plus our Awacs will have mid air refuelling so they are using extra capacity correctly.
