well i think according to current MISHAP scenario we cant trust both of the way of transportation. you all might be aware of recent air crash and train accident.. are there any measures taken there to protect citizens from such mishaps at least from those which happens due to carelessness of human being but not by nature....
We are aware of accidents taking place in both the modes of transport. Well, for me, both can be safe as long as precautions are taken to avoid such mishaps.
As we know both may be safe or not. Its all depends upon the precautions and responsibility of the system of transportation. If they perform their duties with responsibility and follow safety guidelines made for the passengers.
