What is the safest means to travel?

There is no means of transportation that can be considered completely safe. Wherever you are, whatever you do, if accident strikes there's no one who can resist the effects of the outcomes.

Your feet! take a walk!!!!

There is no safest way. Even if you go by foot you could get run over by a drunk driver or trip and hurt yourself.

Going by bicycle would be the safest of the lot, wear protective equipment and a helmet and you should be fine

This is a nice question, I'll tell u what i know,, then u could decide:
If a person used: In regards to SAFETY only
- Walking: could trouble his feet, it could rain on him, a car can hit him, a crazy animal can attach him..

- Balloon: could face difficult wind, rain, could run out of gas, ...

-Para-shoot: he might lose control, again face difficult weather, he can never ensure safe landing, ...

-Car: accidents, speed tickets, car could get hot, lose a tier...

-Bus: same as a car, except for the speed tickets

-Trains: accidents, he could miss his stop, it could be stuck underground,

-Boat: it could sink, could face wind, get sea sick..

-Plane: we all know what could happen

statistically the safest way of traveling is via a elevator. Since you probably mean out of the major forms of getting further than the floor above fly is statistically the safest for accidents per miles traveled.

None really. Just hope for the best. And always wear safty things like seatbelts.
