From: Peter G. Neumann <Neumann@SRI-CSL.ARPA> Ozone is indeed toxic. I am very sensitive to it and other toxins. I have noticed that I have more problems on 767s than any other planes. In talking with pilots and stewardesses on 767 flights, those of them who have thought about it note that they also seem to suffer more on 767s. The apparent problem seems two-fold. One is that 767s fly at altitudes significantly higher than others (e.g., L1011s, 747s, DC10s), typically 41,000 and above, where the ozone is noticeably more prevalent. Second is that the 767 has only one air-conditioning vent in the tail, to minimize drag from the exhaust, whereas the others have several. The result of this seems to be poorer air circulation. In combination, these two factors tend to make the air in 767s much less breathable -- even though the pressurization is of course comparable with that of the other planes. Peter -------
