I didn’ t know that Iceland volcano has erupted, all flights in Europe has been cancelled until Sunday of this week and that Poland’s president, his wife and a daughter died of plane crash related to the volcano eruption as well until Monday this week.  It was one of the biggest events that the world has experienced.  Aviation industry losses $250 million everyday due to closure of airports across Europe. Since airport is closed, that means tourism industry and other businesses would also suffer.  What a great loss for Europe! Well, I hope that this crisis ends soon.  My deepest sympathy to Polish community.
