Here are some other suggestions for survival equipment that can be carried onboard a plane.<br><br>Sewing Kit<br>Super Glue<br>High Energy Food Supplement Bars<br>Credit Cards- Can be sharpened into cutting instruments for emergency situations<br>Aluminum Foil<br>Heavy Duty Aluminum Foil- Like disposible pie plates or disposible oven liners<br>Steel Wool- use a 9 volt battery to start a fire<br>Camera lenses can be used to start a fire<br>Whistle<br>The magnet in earphones can be used to make a compass if you lose your real compass. Actually one of the needles from the sewing kit and a small float can make a compass. Watch "The Empire of the Sun" directed by Steven Speilberg for an example.<br>Can of soda<br><br>As a kid in high school I used to be deathly afraid to walk home through gang infested neighborhoods with the threat of being jumped or getting shot in a drive by shooting. Just before leaving from school I would always buy a can of soda and carry it all the way home without opening it. Why? A can of soda can be used as a weapon if needed. It can be put into a shirt or sack and swung like a mace. It can be used as club in your fist. It can be thrown. It can be shaken up and sprayed into an attacker's eyes. And it can be torn and used as a slashing instrument.<br><br>That soda can can also be used as a pot to boil water, as a signaling device, as a float for fishing, the tab or small piece of the can can be used as a fishing lure, it can be fashioned into a stove, oh...and the contents can be consumed as a refreshing thrist quencher.<br><br>The other thing I did was wear my book filled backpack high on my torso and facing the street. This protected my vital organs from stray bullets that may come my way. It didn't protect my head, but the chances of a bullet hitting my head were smaller than it hitting my body.<br><br><br><br>
