Though no aircraft were truly affected, airline corporations kept their planes grounded, primarily based upon government safety policy. the results of this price the airlines billions of greenbacks, and when being grounded for days, they complained that the govt. agencies creating the selections overreacted to the matter.
In April, ash from Icelandic volcano Eyjafjallajokull (pronounced AY-yah-fyah-lah-YOH-kuul) grounded flights across the world heading to and from Europe for days.

Volcanic ash is created throughout explosive volcanic eruptions, that produce particles consisting of tiny tephra, or bits of pulverized rock and glass. this will be a significant hazard to aircraft as a result of it’s invisible to aircraft weather radar and is commonly not immediately noticed by pilots. Volcanic ash is difficult, doesn’t dissolve in water, is extraordinarily abrasive and mildly corrosive, and conducts electricity when wet.
Aircraft avoid any airspace that has volcanic ash in it for a straightforward reason: the ash will wreck the operate of propeller or jet aircraft. it’s thus fine that it’ll invade the areas between rotating machinery and jam it. The silica melts and fuses on to the turbine blades and nozzle guide vanes (another a part of the turbine assembly), that in fashionable aircraft operate at a far higher temperature than that required for the silica to soften. Aircraft avionics and electronics may be broken. Flying through the ash cloud presents the danger of engine failure, among different potential mishaps.
Considering that almost all airlines are already losing vital amounts of cash and that we are still not nonetheless out of the woods from the worldwide monetary crisis, it’s no surprise that they protested having to possess tens of thousands of flights grounded for days. whereas it’s actually open for discussion whether or not the governments concerned in Iceland’s ash issues overreacted when confronted with having to choose the simplest course of action, there are sound reasons for the priority.
