1. helicopters

   A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common helicopter configuration. However, twin-main rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are sometimes in use due to their greater payload capacity than the monorotor design, and coaxial-rotor, tiltrotor and compound helicopters are also all flying today. Quadrotor helicopters (quadcopters) were pioneered as early as 1907 in France, and along with other types of multicopters, have been developed mainly for specialized applications such as drones.

   It took us two days to get out of Ukraine because of huge traffic jams, everyone was rushing to the border as well. I was driving with military cars on one side and tanks on the other side with Russian helicopters flying above my head. I was very scared for my life and my son’s. There wasn’t enough food, enough water. You especially couldn’t sleep with the sirens going on all the time. Every noise from a car or plane made me look around. I was worried that it was a rocket, a bomb or someone shooting. I can’t even begin to imagine what the people who stayed are going through. I knew I had to survive.
