It is understandable to want to know where to be to increase your case of survival. The best place to be is not where there is a disaster. <br><br>Each of the areas you mentioned has different solutions. Most information I have seen about airplane travel is how to get out of a downed plane. No such opportunity for the four planes 9/11.<br><br>Each of the other forms of transport differ. Generally speaking, limitng the amount travel inside the vehicle by wearing seat restraints decreases injuries during collisions. A bomb exploded underneath a vehicle, the best place to be is not in the vehicle.<br><br>Buildings are a different matter. Fire department ladders cannot reach above 7th or 8th floors. Windows provide an alternate escape out of buildings but provide little blast protection from car bombs outside or vehicles driven into buildings. First floor is easier to get out of but also easier for "bad guys" to get into. Buildings with sprinklers usually only have sprinklers in habitable space. A fire in utility chases will rage unchecked. Manmade fibers are more durable but when burned emit toxic fumes. <br><br>Offices with lots of doors and walls make it more difficult for armed people to negoiate the twists and turns. The doors and walls make good fire breaks but make it more difficult for you to get out. Every choice is a trade-off.<br><br>Maybe if you could start different topics, each about a specific location or scenario, different opinions could be offered.<br><br><br>
