Russian Hypersonic Missile Scientists Arrested for Treason

The arrest of three Russian scientists, including hypersonic researchers, on suspicion of treason has been criticized by members of the Institute of Theoretical and Applied Mechanics (ITAM), who warn that the move has created a chilling effect in the community. The scientists' colleagues have appealed to Russian authorities to "protect Russian aerodynamic science," and warned that staffers now fear being accused of treason for doing their job. The materials of all three criminal cases are closed from the public, but the scientists' colleagues say the acts for which they are accused are considered essential all over the world, including in Russia.
