Air traffic control using two-way radios in planes to communicate to ground operators was developed by the U.S. Army during the Great War. Radio telegraph was sent over distances of 140 miles and messages were exchanged during the flights. Without air traffic control, pilots were isolated from their commanders and unable to communicate their flight paths and any problems they may be encountering. To this day, the thousands of daily flights across the globe would not be possible without air traffic control being established in every country. Another great technological invention was the mobile x-ray machine. As millions of soldiers were suffering life-threatening injuries, diagnosing the medical conditions was challenging without having access to x-ray equipment that would be found at hospitals. Marie Curie created a mobile x-ray station for the French military that was transported in small trucks and cars, that were able to be sent to the surgical stations at the front lines. With the success of these machines, further development by other inventors introduced smaller portable x-ray machines. Other inventions included aircraft carriers and tanks. The thought of launching and landing an aircraft from a moving ship was unheard of but when a small pontoon biplane was piloted off a ramp of a ship deck, it was the beginning of future aircraft carriers. As long platforms were being built on these ships, airplanes had the additional space to launch and land safely on these large ships as well as being stored in hangars inside the ships. As for tanks, the front lines were seen with trenches and massive rifle fire but once an armoured vehicle was built that could withstand gun fire and drive across rough terrain, the use of a tank was just the beginning. Tanks were used to get to the other side of the front line and get up close with
