What is the dearest plane in the world?

Answer 1

This is a tough question to answer as asked. In terms of cost per unit model, today's jumbo jets like the Boeing 787, 747-800, and Airbus 380 can cost upwards of 300 million dollars each depending on how the carrier wants it equipped. On the other hand, if you include development costs, the numbers skyrocket. Reportedly, the Concord development costs exceeded the equivalent of some 2 billion in today's dollars. Finally, there is no way to calculate the development costs of military aircraft such as the SR-71.
