How can it’s possible to take so long to have an operator Certificate, when you have a 747 ready to fly on ground?
You apparently do not have any concept of the MANY facets of requirements and qualifications that precede an AOC. Training, Maintenance, Ground Handling, Safety, Dispatch, and Operations manuals and procedures must be developed and approved. People must be found to generate the manuals, become qualified as trainers, and find & train the workers. Then the inspectors have to observe and approve a round of proving flights performed by the trained & qualified workers.
It's a LOT more involved than buying an airplane and finding a couple pilots to fly it...
