There is a crash switch on the belly. >I would have thought that cabin pressure alone was sufficient in preventng >them from being opened during flight. Only if they are a plug type door. Many are not, and are only retained by the locking mechanism (which usually incorporates a mechanism/construction to prevent opening if cabin pressure exceeds certain limits. There is also the fact that not all parts of an A/C flight will require pressurisation, and of course, during take off and landing, any pressure differential present MUST allow the doors to function (a very important error made in the L-1011 deaths in Riyadh).
