The British Navy demonstrated a real-life suit that can help a soldier to fly in the same manner as Iron man from the MCU.
The Jet suit is created by the ex-navy Richard Browning expert and cost about $340 000. It gives the chance for the seals to board a ship in an unconventional way and surprise the enemy.
The suit has 5 rocket engines and a backpack full of electronics and fuel.
The maximum speed is 50 km/h and the maximum altitude is about 3500 meters. However, there is no information on the length of the flight.
It is cool to see something like that possible in the real world.
