hello! I recently flew from Athens to London, with regular flight. I noticed that a significant part of the whole travel time is taken by the take off and landing. Why don't we develop a system, similar to helicopters, in order to achieve the fastest take off and landing? Also, I wonder why the plane couldn't just fly faster after taking off and before landing. Can't the human sustain such accelerations and velocities? We don't have the technology to fly that fast? What is the problem exactly? I strongly believe that with current technology it would be possible to diminish the flight duration to a fraction of its current amount. We already have airoplanes that drive much faster. Also, human body can sustain faster velocities and accelerations I believe. Current accelerations in a regular airoplane are not even noticeable! Any thoughts? Thanks!
