This aircraft is a very very high risk aircraft and is heavily dependent on electrical circuits. If circuits fail, it will not be easy to control. Due to its very heavy weight, it is a high risk in turbulence. Moreover if it nose dives what happens to swimming pool water? And in case of emergency it cannot be rerouted to nearest airport. Till date, we do not know if it can glide like the other aircrafts if machines fail. And all its economics assumes that it will be fully loaded so today it will fly on heavy traffic routes. When it is not so, what will happen? And this is just the beginning and it has not yet shown its full colors yet. So it remains to be seen if it wil head the concorde way
