Les mystères de l'Accident de décompression (ADD)

De la mer à l’espace
Les environnements sous-marins permettent de simuler les conditions de l’exploration spatiale et offrent à la NASA un cadre pour tester du matériel, mener des recherches et préparer de futures missions dans des environnements extrêmes, tels que la Lune ou Mars. L’immersion sous l’eau recrée l’isolement, les espaces confinés et les ressources limitées auxquels les astronautes sont confrontés dans l’espace.

Je souscris toujours une assurance voyage DAN pour mes voyages à l’étranger, ce qui me procure une tranquillité d’esprit au cas où un imprévu surviendrait.

Exiting a Plane During an Emergency
Most flights are uneventful, with the worst experiences being an occupied lavatory or unexpected turbulence. Emergencies can happen, however, and aircraft passengers need to be prepared to react quickly and efficiently. In an emergency, knowing the proper evacuation procedures for your flight can mean the difference between safely concluding your trip or reaching a different final destination.
