The least popular variant of the 747 has been unexpectedly brought back into commercial service after being absent for almost 2 years. A few weeks ago, Iranian based carrier “Mahan Air” reactivated one of their old 747-300s after it had been on the ground since 2015. Only 81 747-300s were ever built, and almost all of them are retired. As of 2020, the only 747-300 that remained in operation was a cargo plane owned by Trans Avia Export Cargo Airlines. The return of such an uncommon plane for passenger use is certainly a rare and surprising occurrence. In this article, we will be explaining why Mahan Air brought back and revived the 747-300.

Almost 50 years ago, the first commercial supersonic jet was introduced into the world, revolutionizing air travel and opening a new chapter in the way people flew. Flying at 2 times the speed of sound and faster than the spin of the Earth, Concorde was a peak of innovation in aviation, and it allowed people to travel across the Atlantic Ocean in just 3 hours. Today, however, the time of flight for the same distance is double. In this sense, aviation seems to have taken a step backwards since the Concorde. If no level of innovation could match that of the Concorde, then why exactly was it retired?
