ASTONISHING footage has emerged showing a Russian pilot flying the Kremlin’s new Su-57 stealth fighter jet without a ROOF on his cockpit.
The daredevil flier is seen at the controls of the 1,300mph state-of-the-art warplane, but the main protective covering is clearly missing.
The footage has just been released by bosses at Vladimir Putin's defence ministry.
The plexiglass canopy covering the top and sides of the cockpit prevents the pilot from freezing to death.
It is believed to have been removed as part of a test of emergency procedures should the aircraft get into trouble ahead of ejection.
Analysts say the pilot is wearing a special suit as protection against the shocking cold at extreme heights.
The ministry did not give details of the altitude, speed or purpose of the flight.
The warplane is designed to carry the advanced Kinzhal hypersonic nuclear-capable missile which operates at ten times the speed of sound.
The ‘topless’ flight took place over the Chkalov Test Centre at Akhtubinsk, Astrakhan region.
The Su-57, known to NATO as Felon, is also seen carrying new “modernised” variant of the Russian R-77-1 medium-range active-homing air-to-air missile, say observers.
