There are plenty of people that have a fear of flying, but heck, that is flying on normal, commercial aircraft which is statistically seen as the safest mode of traveling for passengers, so the fear that certain passengers have is basically unfounded. On the other hand, you have military aircraft that must take off and land onto aircraft carriers, and in a time of war, also take care of delivering their military payload onto the intended target(s), or whatever assignment that has been given to that particular aircraft pilot. The sheer audacity of aircraft landing onto a moving aircraft carrier that is situated on an unstable and moving surface, which is an ocean, on a runway which is both short and unforgiving is absolutely staggering, yet it is done, time and time again, successfully.
Even the taking off on an aircraft carrier is an exercise in precision, as an airplane needs appropriate velocity in order to take off successfully, unlike commercial airports, the runway on an aircraft carrier is not long enough, so there are two basic things that are needed to aid an aircraft in taking off; the first is the speed of the carrier itself, which helps to generate necessary wind speed, and along with a special catapult utilized depending upon the carrier, and with an airplane track to both help guide and to assist the plane into reaching the velocity needed for takeoff, the actual takeoff is accomplished.
After the mission is accomplished the aircraft must land back onto the aircraft carrier. The first step towards a successful landing is lots and lots of simulated landings, the second step is lots and lots of practice landing on a special auxiliary landing field over and over again, and the final step is the actual landing onto a real aircraft carrier. As you might imagine, despite all the practice, despite all the technological equipment, despite all the instruction, the actual landing is intricate, involving not only the pilot, the aircraft, the aircraft carrier, aircraft equipment, but also specific personnel on the aircraft carrier that work in conjunction with the pilot to assure that the landing is successful, to which you as a pilot have to not only slow your aircraft down to a sustainable speed that will not stall your plane out, but also to a speed that will allow you to successfully time your landing of your craft onto a moving aircraft carrier.
Because the world is about 70% water based, an aircraft carrier is of invaluable assistance because of its ability to get to just about any area of the world, and thereby allowing the aircraft onboard to deliver their payloads or accomplish other tactical missions, especially in places to which there are no nearby land or naval airbases. The mobility of our aircraft carriers as well as the aircraft that they contain, allows the United States, to provide a meaningful presence in virtually any corner of this globe, as having preeminent control of both land and sea is a key component towards providing security through strength.
