When flying out of Joburg we are told that we HAVE to carry and matches or lighters on our person, and NOT in our check in baggage or even carry on baggage. This is because of incidents when matches or lighters have spontaneously combusted in baggare or hand baggage. Theory is that is if lights up in your trouser pocket and you and everyone around is immediately aware of the problem!!!!
Interestingly I have not seen this instruction giving at any other airports LHR,Frankfurt,Miami etc where I have been recently. <img src="rolleyes.gif" border="0">
