Translate the following English sentence to French:
". (PT) Although this report deals with certain real situations, such as the increase in air traffic or the delays experienced on various routes, and although it is based on certain correct premises, specifically the need to guarantee and strengthen air transport safety, it nevertheless glosses over the underlying causes of these situations, which are inextricably linked with successive actions to liberalise air transport and with the unbridled competition that has resulted from this."
Le présent rapport, tout en partant de certaines situations réelles - comme l'augmentation du trafic aérien ou les retards constatés sur certaines routes - et de certaines affirmations correctes - en particulier la nécessité de garantir et renforcer la sécurité du transport aérien -, escamote cependant les causes profondes de ces situations, qui sont indissociables des libéralisations successives au niveau des transports aériens et de la concurrence effrénée qui en découle.
