No we don't fly unless completely necessary. !0% fresh air only. Yech.
and of course this,
"Finally, consider a remark made by a Boeing physicist that the pollution levels from one 747 take-off are somewhat similar to setting the local gas station on fire and flying it over your head."http://www.areco.org/deadly.htm
"Harmful as noise may be, its effects may be minor when the products of jet engine exhaust and other airport sources are considered. I, and other members of the Alliance of Residents Concerning O’Hare (AReCO) and our recently organized national organization, US-Citizens Aviation Watch (US-CAW), with the Natural Resources Defense Council have come upon much interesting information about airport and aircraft operations, which produce massive amounts of hazardous and toxic emissions.
Here is just a partial, astonishing list of constituent compounds: Freon 11; Freon 12; Methyl Bromide; Dichloromethane; cis-l,2-Dichloroethylene; 1,1,1-Trichloroethane; Carbon Tetrachloride; Benzene; Trichloroethylene; Toluene; Tetrachloroethene; Ethylbenzene; m,p-Xylene; o-Xylene; Styrene; 1,3,5-Trimethylbenzene; 1,2,4-Trimethylbenzene; o-Dichlorobenzene; Formaldehyde; Acetaldehyde; Acrolein; Acetone; Propinaldehyde; Crotonaldehyde; Isobutylaldehyde; Methyl Ethyl Ketone; Benzaldehyde; Veraldehyde; Hexanaldehyde; Ethyl Alcohol; Acetone; Isopropyl Alcohol; Methyl Ethyl Ketone; Butane; Isopentane; Pentane; Hexane; Butyl Alcohol; Methyl Isobutyl Ketone; n,n-Dimethyl Acetamide; Dimethyl Disulfide; m-Cresol; 4-Ethyl Toulene; n- Heptaldehyde; Octanal; 1,4-Dioxane; Methyl Phenyl Ketone; Vinyl Acetate; Heptane; Phenol; Octane; Anthracene; Dimethylnapthalene(isomers); Flouranthene; 1-methylnaphthalene; 2-methylnaphthalene; Naphthalene; Phenanthrene; Pyrene; Benzo(a)pyrene; 1-nitropyrene; 1,8-dinitropyrene; 1,3-Butadiene; sulfites; nitrites; nitrogen oxide; nitrogen monoxide; nitrogen dioxide; nitrogen trioxide; nitric acid; sulfur oxides; sulfur dioxide; sulfuric acid; urea; ammonia; carbon monoxide; ozone; particulate matter (PM10, PM2.5); and finally this compound; 3-nitrobenzanthrone.*
According to chemist Hitomi Suzuki of Kyoto University, the last compound, 3-nitrobenzanthrone, may be the most hazardous compound ever to be tested for carcinogenicity, scoring substantially higher in the well-known Ames test than its nearest rival, 1,8-dinitropyrene listed above. (New Scientist, 25 October 1997.) Many of the other compounds indicated above are also considered to be carcinogens. Adding to the direct effect of any single chemical listed above, the probabilities of synergistic effects must be considered. The toxic brew of compounds is also subject to reactions caused by atmospheric and solar effects, resulting in new, consequent compounds. "
Kinda takes the wind out of the anti-smoking rage we so often see here.
Kettle, meet pot.
