The F-4 Phantom II was the United States' primary air superiority fighter aircraft during the Vietnam War. This airplane epitomized American airpower doctrine during the early Cold War, which diminished the role of air-to-air combat and the air superiority mission. As a result, the F-4 struggled against the Soviet MiG fighters used by the North Vietnamese Air Force. By the end of the Rolling Thunder bombing campaign in 1968, the Phantom traded kills with MiGs at a nearly one-to-one ratio, the worst air combat performance in American history. The aircraft also regularly failed to protect American bombing formations from MiG attacks. A bombing halt from 1968 to 1972 provided a chance for American planners to evaluate their performance and make changes. The Navy began training pilots specifically for air combat, creating the Navy Fighter Weapons School known as "Top Gun" for this purpose. The Air Force instead focused on technological innovation and upgrades to their equipment. The resumption of bombing and air combat in the 1972 Linebacker campaigns proved that the Navy's training practices were effective, while the Air Force's technology changes were not, with kill ratios becoming worse. However, the last three months of the campaign introduced an American ground radar system that proved more effective than Top Gun in improving air-to-air combat performance. By the end of the Vietnam War, the Air Force and Navy overcame the inherent problems with the Phantom, which were mostly of their own making.

Abstract This research on military aviation noise was conducted because the personnel working with military aircraft were concerned about noise induced hearing damage. In addition, comprehensive data on hearing impairments and occupational exposure of military pilots in the Finnish Air Force was not available. Moreover, data on the effects of overflight noise of military jets was necessary for the evaluation of noise induced hearing deteriorations of members of the public who might be exposured accidentally for the low-level jets' overflights. The averaged noise exposure levels of pilots varied during a flight from 97 dB(A) to 106 dB(A) in the cockpit and from 83 dB(A) to 100 dB(A) at the entrance of the ear canal. Radio noise was 4–10 dB higher than background noise inside the helmet. The attenuation provided by air crew helmets varied from10 to 21 dB(A) in the laboratory, and was at the same level during real flights. The attenuation measured in the laboratory and in working conditions was about 30 dB(A) for earmuffs. An active noise cancellation (ANC) device decreased averaged noise exposure (LAeq8min) 4–8 dB over the noise attenuation of the same helmets when the ANC system was off. The noise of overflights by military jets were measured and the noise levels were lower than those known to cause the permanent threshold shifts. However, noise induced hearing damages might be possible in certain conditions. In order to assess the hearing loss risk of pilots, hearing thresholds were measured before and after one flight using both conventional and extended high frequency (EHF) audiometry. Minor temporary threshold shifts (TTS) were revealed. The risk of noise-induced damage at the studied exposure levels is, in all probability, rather small. A novel NoiseScan data management system proved to be an interesting tool in assessment of the risk of developing hearing impairment on the basis of known risk factors. Due to the small number of risk factors, the hearing of pilots was shown to be at considerably less risk than that of industrial workers in Finland.

Les bases aériennes sont des éléments incontournables de la puissance aérienne car sans infrastructures dédiées, l’aviation militaire est inopérante. La répartition géographique des bases aériennes répond à des stratégies politiques, militaires mais également économiques. Elles en sont les traductions spatiales. De fait, organisées en réseaux, les bases aériennes concourent à définir la géostratégie aérienne. L’analyse spatiale et historique du réseau des bases aériennes françaises depuis le début du XXe siècle démontre la place prégnante de ce maillage dans la stratégie française et constitue le reflet de la perception de la France de son espace environnant. D’abord, le réseau illustre, dans la stratégie territoriale française, la prééminence d’une posture défensive du sanctuaire métropolitain, à l’origine d’une « France différenciée » dont le découpage territorial s’effectue selon la répartition des types de bases aériennes. Ensuite, le réseau des bases aériennes extra-métropolitaines, à la différence de sa consœur métropolitaine, n’est pas seulement régi par une stratégie de défense. Dans un premier temps, dans le cadre de sa politique coloniale, la France utilise son réseau comme instrument d’exploration, de contrôle et conservation de territoires ; puis, dans le cadre de sa politique étrangère, elle s’en sert comme d’un moyen de préservation de ses intérêts vitaux dans les pays étrangers et les territoires français d’outre-mer. / Air bases are inescapable elements of air power because without dedicated infrastructures, military aviation is ineffective. The geographical distribution of air bases answers political, military but also economic strategies. Air bases are the spatial translation of these strategies. In fact, air bases organized in networks contribute to define the air geostrategy. The spatial and historical analysis of the French air bases network since the beginning of the XXth century demonstrates the prominence of this web in the French strategy and reflects the French perception of its surrounding space. First the network illustrates the superiority of a defensive posture of the metropolitan sanctuary in the French territorial strategy, at the origin of a “differentiated France” sub-divided according to the distribution of various air base types. Then, the overseas air bases network, unlike its metropolitan counterpart, is not governed solely by a defense strategy. Within the colonial policy framework, France uses its network as instrument of exploration, control and preservation of territories. In addition, within the foreign policy framework, France uses it as of a means of conservation of its vital interests in foreign countries and French overseas territories.

<p>In the essay, the view of mistakes and disciplinary sanctions within the military aviation and health and medical service, are compared. The comparison shows that military aviation and health and medical service could have several points in common on how mistakes may occur, but that the present view of mistakes is different betwen the sectors. The view of mistakes and disciplinary sanctions is explicit within military aviation, and is based on a clear ideology on how mistakes occur, which is characterised of a systematic approach. Within health and medical service, an explicit and unequivocal ideology on how mistakes occur is missing, but, however, there are implicit ideas about infallibility and perfection. The comparison indicates that the view of mistakes is also, possibly directed by a bureaucratic model (instead of an ideology on mistakes), which aims to legitimacy, but that this may happen on the expense of not taking surrounding circumstances into consideration. In that way there may be a certain contrast in the health and medical service’s present system between rule of law and medical service safety.</p>
