Kudos to Ukrainian President Zelenskyy for keeping himself together after Trump‘s statement that „Russia wants Ukraine to succeed“. I would have bursted out laughing. But his facial expressions are priceless.

Rather shocking, assuming it's genuine. Whilst it would undoubtedly save on hangar space, aircraft typically aren't designed to fold like this.

Ukrainian strike on the Russian An-26 aircraft is a unique operation.
You can see on the video that the rotors are moving and the engine nozzle is hot. Fuel tanks were full, and looks like the aircraft was ready for takeoff.
Perfect timing for a strike!
Glory!

The F-14’s Wing Center Section (WCS) is made of Ti-6Al-4V α–β titanium alloy in the annealed state (UTS ≈ 896 MPa), probably the most commonly used titanium alloy in the aerospace industry. The structure assembled by electron-beam welding (EBW).
