I have never observed mosquitos in an airplane. Nevertheless, I'd say they would be flying in the same speed they would if the airplane was landed. At least relative to the passangers and the airplane itself. For the time being, I see no reason for thinking their speed would be different (we don't walk slower or faster when we are inside a flying airplane, do we?) On the other hand, it may well be the case that the low air pressure, lack of oxygen, and cold air inside a airplane render the mosquitos lethargic. We must bear in mind that air companies, in order to save money, keep a very low rate of air exchange. This brings oxygen to very low levels. Some death and many problems during or immediately after flights can be traced to this oxygen deficit. Also to save money, airplanes are never fully pressurized. They are kept as if we were at altitude of about 2,100 m so oxygen partial pressure is lower. Add these two factor together and we conclude passangers (mosquitos included) can not afford to produce dynamic energy (no oxygen, no energy!). If your observation in that flight represents the reality for every flight, then perhaps we should learn a lesson with the mosquitos: hybernate during flights if cabin is pressurized. :-) - fernando keep us under -- REDUZIR, REUSAR, RECICLAR -- Dever de todos, amor aos que vir�o REDUCE, REUSE, RECYCLE -- Everybody's duty, love to those who are to come Fernando Cabral Padrao iX Sistemas Abertos mailto:[EMAIL PROTECTED] http://www.pix.com.br Fone Direto: +55 61 329-0206 mailto:[EMAIL PROTECTED] PABX: +55 61 329-0202 Fax: +55 61 326-3082 15� 45' 04.9" S (23 L 0196446/8256520) 47� 49' 58.6" W 19� 37' 57.0" S (23 K 0469898/7829161) 45� 17' 13.6" W
