The smaller size and lighter weight of the Boeing 747SP aircraft, introduced into passenger service in 1976, permitted higher-altitude flight than older commercial aircraft and thus potentially greater ozone exposure for those of board. Concerned flight attendants distributed questionnaires relating to symptoms experienced on the Boeing 747SP and/or conventional 747 aircraft to Los Angeles- and New York-based flight attendants. Respondents reported symptoms by frequency and severity and by in-flight and after-flight occurrence. Based on the assessment of three health scientists as to ozone-relatedness, the frequency of "definite" and "probable" ozone-related symptoms of any severity reported by both groups of attendants was significantly associated with 747SP flights (chi-squares: P less than 0.05). After-flight symptoms significantly associated with 747SP experience, although fewer in number than in-flight symptoms, were all in the scientists' "definite" category. In 21 flight attendants who complained of moderate to severe symptoms during 747SP flights, a battery of pulmonary function tests performed approximately two weeks after their last 747SP flight failed to reveal abnormalities. The symptom questionnaire results are consistent with possible exposure of cabin attendants to toxic levels of ozone during the higher-altitude flights of the Boeing 747SP compared to conventional 747 aircraft.
1976年投入客运服务的波音747SP飞机尺寸更小、重量更轻，与老式商用飞机相比，它能够在更高的 altitude 飞行，因此机上人员可能会受到更多的臭氧 exposure。忧心忡忡的空乘人员向洛杉矶和纽约的空乘人员发放了有关在波音747SP和/或传统747飞机上所经历症状的问卷。受访者按频率、严重程度以及飞行中和飞行后出现的情况报告症状。根据三位健康科学家对与臭氧相关性的评估，两组空乘人员报告的任何严重程度的“明确”和“可能”与臭氧相关症状的频率与747SP航班显著相关（卡方检验：P小于0.05）。与747SP飞行经历显著相关的飞行后症状，尽管数量比飞行中症状少，但都属于科学家们的“明确”类别。在21名在747SP航班上抱怨有中度至重度症状的空乘人员中，在他们最后一次747SP飞行大约两周后进行的一系列肺功能测试未发现异常。症状问卷结果与空乘人员在波音747SP的高空飞行过程中可能接触到有毒水平的臭氧一致，而传统747飞机则不然。
