The Boeing 747 and the Airbus A380 are both large commercial aircraft that have been in service for several decades. Both have had significant impacts on the aviation industry, but have had different operational histories.
The Boeing 747, also known as the "Queen of the Skies," made its first flight in 1969 and was the first wide-body commercial jet. It has been produced in several variants, including the 747-100, 747-200, 747-300, 747-400, and 747-8. The 747-400, which was introduced in 1989, was the most popular variant and was operated by numerous airlines worldwide. The 747 has been used primarily for long-haul flights, carrying both passengers and cargo. However, the 747 program saw a decline in orders in recent years, and the production was stopped in 2019.
The Airbus A380, on the other hand, made its first flight in 2007, and was the first superjumbo jet in the world. The A380 was designed to compete with the 747 and to be used primarily for long-haul flights, with a capacity of up to 853 passengers. However, the A380 program did not do as well as expected, with the lack of demand, high development costs and operational challenges. Only a single variant, the A380-800, was produced, and only a limited number of airlines have ever operated the aircraft. The A380 program was discontinued in 2019.
In summary, The 747 program has a long operational history and has been successful, but the demand for large wide-body aircraft has been decreasing, so the program was stopped. The A380 program, on the other hand, had a shorter operational history and had a limited success, due to the lack of demand and operational challenges.
