What a difference some years can make. On the right here is the P-51. This plane was a standard during WWII and Korea. It was used by many nations. At the start of Korean War, the Mustang was the main fighter of the United Nations until jet fighters such as the F-86 took over this role; the Mustang then became a specialized fighter-bomber. Despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After World War II and the Korean War, many Mustangs were converted for civilian use, especially air racing. There were around 15,000 of them produced. There are still around 70 of them flying today The cost of the airplane was around $51,000.00
Now we have the DRONE. Unmanned aerial vehicles (UAVS), also known as drones, are aircraft either controlled by ‘pilots’ from the ground or increasingly, autonomously following a pre-programmed mission. (While there are dozens of different types of drones, they basically fall into two categories: those that are used for reconnaissance and surveillance purposes and those that are armed with missiles and bombs. The use of drones has grown quickly in recent years because unlike manned aircraft they can stay aloft for many hours (Zephyr a British drone under development has just broken the world record by flying for over 82 hours nonstop); they are much cheaper than military aircraft and they are flown remotely so there is no danger to the flight crew. They cost around 3 or 4 million dollars.
