In the early years of World War II, it was an amazing feat for an Allied airman shot down over occupied Europe to make it back to England. By 1943, however, pilots and crewmembers, supplied with \"escape kits,\" knew they had a 50 percent chance of evading capture and returning home. An estimated 12,000 French civilians helped make this possible. More than 5,000 airmen, many of them American, successfully traveled along escape lines organized much like those of the U.S. Underground Railroad, using secret codes and stopping in safe houses. If caught, they risked internment in a POW camp. But the French, Belgian, and Dutch civilians who aided them risked torture and even death. Sherri Ottis writes candidly about the pilots and crewmen who walked out of occupied Europe, as well as the British intelligence agency in charge of Escape and Evasion. But her main focus is on the helpers, those patriots who have been all but ignored in English-language books and journals. To research their stories, Ottis hiked the Pyrenees and interviewed many of the survivors. She tells of the extreme difficulty they had in avoiding Nazi infiltration by double agents; of their creativity in hiding evaders in their homes, sometimes in the midst of unexpected searches; of their generosity in sharing their meager food supplies during wartime; and of their unflagging spirit and courage in the face of a war fought on a very personal level.

Pilots are crucial to the safety of the airline industry; as a result, their sleep and biorhythm, which are closely related to fatigue, play an important role. During the COVID-19 pandemic, the Civil Aviation Administration of China exempted flight crews from mandatory layovers and imposed limitations on duty period and flight times. Given that the effect of this policy on their sleep and biorhythm is poorly understood, this study explores the key factors affecting the sleep and biorhythm of pilots on intercontinental flights and compares the rest status on and after flying days on exempt and non-exempt flights. Eighty pilots flying from China to five countries wore a body movement recorder, which has been validated for estimating total sleep time, sleep efficiency, and interdaily stability. The results of the K-means clustering analysis showed differences in sleep and biorhythm on flying days between departures during the day and at night, west–east and north–south flights, and exempt and non-exempt flights. ANOVA was performed based on the categorization in which each indicator contributed significantly to the clustering ( p  = 0.000). This study contributes to the literature by validating a new intercontinental flight operation model under the COVID-19 pandemic conditions and proposes critical points for the future management of pilot fatigue on long-haul flights.

Background Commercial airline crew is one of the occupational groups with the highest exposures to ionising radiation. Crew members are also exposed to other physical risk factors and subject to potential disruption of circadian rhythms. Methods This study analyses mortality in a pooled cohort of 93 771 crew members from 10 countries. The cohort was followed for a mean of 21.7 years (2.0 million person-years), during which 5508 deaths occurred. Results The overall mortality was strongly reduced in male cockpit (SMR 0.56) and female cabin crews (SMR 0.73). The mortality from radiation-related cancers was also reduced in male cockpit crew (SMR 0.73), but not in female or male cabin crews (SMR 1.01 and 1.00, respectively). The mortality from female breast cancer (SMR 1.06), leukaemia and brain cancer was similar to that of the general population. The mortality from malignant melanoma was elevated, and significantly so in male cockpit crew (SMR 1.57). The mortality from cardiovascular diseases was strongly reduced (SMR 0.46). On the other hand, the mortality from aircraft accidents was exceedingly high (SMR 33.9), as was that from AIDS in male cabin crew (SMR 14.0). Conclusions This large study with highly complete follow-up shows a reduced overall mortality in male cockpit and female cabin crews, an increased mortality of aircraft accidents and an increased mortality in malignant skin melanoma in cockpit crew. Further analysis after longer follow-up is recommended.

Recent infectious disease outbreaks highlight the importance of competent professionals with expertise on public health preparedness and response at airports. The availability of a competency profile for this workforce supports efficient education and training. Although competency profiles for infectious disease control professionals are available, none addresses the complex airport environment. Therefore, the main aim of this study is to develop a competency profile for professionals involved in infectious disease preparedness and response at airports in order to stimulate and direct further education and training. We developed the competency profile through the following steps: 1) extraction of competencies from relevant literature, 2) assessment of the profile in a national RAND modified Delphi study with an interdisciplinary expert group (n = 9) and 3) assessment of the profile in an international RAND modified Delphi study with an airport infectious disease management panel of ten European countries (n = 10). We systematically studied two competency profiles on infectious disease control and three air transport guidelines on event management, and extracted 61 relevant competencies for airports. The two RAND modified Delphi procedures further refined the profile, mainly by specifying a competency's target group, the organizational level it should be present on, and the exact actions that should be mastered. The final profile, consisting of 59 competencies, covers the whole process from infectious disease preparedness, through the response phase and the recovery at airports. We designed a profile to support training and exercising the multidisciplinary group of professionals in infectious disease management in the airport setting, and which is ready for use in practice. The many adaptations and adjustments that were needed to develop this profile out of existing profiles and air transport guidelines suggest that other setting-specific profiles in infectious disease control are desirable.

According to the International Air Transport Association, the industry fuel bill accounts for more than 25% of the annual airline operating costs. In times of severe economic constraints and increasing fuel costs, air carriers are looking for ways to reduce costs and improve fuel efficiency without putting flight safety into jeopardy. In particular, this is inducing discussions on how much additional fuel to put in a planned route to avoid diverting to an alternate airport due to Air Traffic Flow Management delays. We provide here a general model to support such decisions. We illustrate it with a case study and provide comparison with the current practice, showing the relevance of our approach.
