Asthma from traffic
Asthma is a serious medical condition because it is lifelong; there is no cure. A study says that pollution from traffic connects to 4 millions new cases of asthma in children each year.
Researchers studied the pollution and how it affects children’s health in 194 countries and 125 large cities.
This is not the first study to make this clame, but the study’s main author says that it gives a comprehensive idea of the problem. She says that it tells where pollution “hot spots” are.
Some people think rules for pollution need to change and that we need to have cleaner transportation. The author also said that there are other pollutants in the world causing diseases, such as lung cancer, strokes, heart disease and developmental issues.

Iceberg ruptures in Patagonia raise alarm about global
warming
Fabian Andres Cambero
Two new icebergs have broken off from the Grey Glacier in Chile’s Patagonia in recent weeks. Scientists have linked the increased frequency ice breaks to rising temperature. According to Ricardo Jana, researcher and member of the climate change area of the Chilean Antartic Institute (INACH) “In recent years temperature rises above the normal average and intense rainfall were registered with an increase in water level in the lake, factors that could explain the separation. Reseachers from universities in Germany and Brazil, together with experts from INACH and other local entities, have been studing the Grey Glacier since 2015.

Reasons why the Airbus A380 failed
On 14 February 2019, Airbus announced their A380s have been cancelled, with production ending in 2021. After 12 years of shaky business and development, its closure didn’t come as a surprise. The dream is over for the world’ largest passenger airliner. Why was the king of the airliners forced to land so quikly? Here’s what happened:
!$ \bullet !$ poor business planing finds itself at the heart of the A380’s downfall. Most of all A380’ eggs were put in a basket called Emirates, Airbus biggest buyer.
!$ \bullet !$ bigger isn’t always better. With a wingspan of almost 80 meters was difficult to guide the giant four-turbine around airports.
!$ \bullet !$ airbus failed to antecipate how consumer’s tastes in air travel would change over the years. Passengers nowadays prefer smaller airports, using direct routes to their destinations.
!$ \bullet !$ although a seating capacity of 800 may seem impressive at first, it is not easy to fill them up, even when you give discounts and make promotions.
Airbus A380’ closure perhaps teaches us all a lesson or two. Dream big, but keep your feet on the ground.

The plane, the pilot and the mechanic.
Whereas, several test pilots might fly the prototype, each prototype is enrusted to only one mechanic. For him, I’m the pilot who is going to fly “his” plane and furnish him with the proof that the work he has lovingly and conscientiously put it on it all day, and sometimes all night, has not been in vain. The relation between the pilot, the plane and the mechanic are at once very simple – basic, obviously – and very complex when it comes to putting them into words. For the mechanic, the plane is a kind of Sleeping Beauty, and he takes care of her and coddles her while she is asleep. As soon as she wakes up, she passes into the hands of the pilots, but he only knows the plane when it is “alive”, when it is flying and functioning. The moment the plane takes off for a test, the mechanic loses sight of it, but he follows it, he feels it, he is bound to it by a kind of sixth sense, or to put it better, by an invisible umbilical cord.
