Wikipedia Reference desks Hello Aspro On 11 July you replied to a question asked at Wikipedia Reference desk Science The question related to Airliner cabin air See your diff Your answer included the following statements The banning of smoking also meant that the amount new air added to the cabin could be reduced thus saving the costs of pressurizing greater amounts of air to keep the interior atmosphere agreeable To save more costs they also reduced in the last decade the cabin pressure but to the detriment of passengers suffering from emphysema and other medical conditions that low air pressure can aggravate To counter the possible resulting in flight emergencies from this new practice some air lines are now carrying portable automatic heart defibrillators on board To support your answers you supplied a link to a website that discusses spraying of insecticides on airliners I have looked at that website but found nothing to support the statements I have pasted above I have also looked at the Wikipedia article on Cabin pressurization but I found no information of the kind you gave in your answer It looks to me like you have used the opportunity given by this question to respond with some of your original research It looks to me very much like your own conspiracy theory or someone else s conspiracy theory to which you have enthusiastically subscribed Wikipedia s reference desks are intended as places where Users from around the world can ask serious questions and receive high quality answers I think your answer was a very poor one so I ask that in future if you can t find the answer using the resources of Wikipedia or some other reliable published source don t answer the question Certainly don t use the reference desks as vehicles for your own original research or your favourite conspiracy theory Before I write anything more I am interested in whatever comment you wish to make about my criticism
