Microburst Most Likely Struck AIRES Flight in San Andrés Island

"I felt the plane descending too fast as if we were in vacuum  and following I only saw a intense brightness in the sky", said a Brazilian victim of the crashed airplane .

Another Brazilian passenger told to a Brazilian TV channel  reporter, "It was raining a lot with lightnings surround the plane as all of us could see outside the plane but there was no affliction by the passengers. The approach for landing it was apparently normal for us. Suddenly the plane started descending more fast and struck the ground abruptly".

A microburst often causes aircraft to crash when they are attempting to land (except Pan Am Flight). The microburst is an extremely powerful gust of air that, once hitting the ground, spreads in all directions. As the aircraft is coming in to land, the pilots try to slow the plane to an appropriate speed. When the microburst hits, the pilots will see a large spike in their airspeed, caused by the force of the headwind created by the microburst. A pilot inexperienced with microbursts would try to decrease the speed. The plane would then travel through the microburst, and fly into the tailwind, causing a sudden decrease in the amount of air flowing across the wings. The sudden loss of air moving across the wings causes the aircraft to literally drop out of the air. The best way to deal with a microburst in an aircraft would be to increase speed as soon as the spike in airspeed is noticed. This will allow the aircraft to remain in the air when traveling through the tailwind portion of the microburst and also pass through the microburst with less difficulty, although it is possible that for light aircraft, the descent rate induced by the microburst will exceed their maximum climb rate, leading to an unavoidable crash.)

A aeronave sofreu acidente às 06:49 GMT(03:49 Hora de Brasília), enquanto estava pousando na ilha San Andrés, Colômbia, a qual é uma ilha tipo resort com uma população de 178.000 habitantes e fica distante 190 Km da costa da Nicarágua.

The scale and suddenness of a microburst makes it a great danger to aircraft, particularly those at low altitude which are taking off and landing. The following are some fatal crashes that have been attributed to microbursts in the vicinity of airports:
