a string of air show disasters. in september 2011, ten bystanders and the pilot were killed in this crash at the reno nevada air races. debris flying into the crowd. in 2013, a wind walker and her pilot died in this fiery crash. and in 1988, 70 were killed, and hundreds injured in ramstine, germany, when this stunt went terribly wrong. as this latest investigation gets under way, it has many asking are air shows too dangerous. what is the audience looking for? they re looking for thrills. oh, my goodness, how are they going to pull out of that. and sometimes they don t. reporter: there was a moment of silence this morning to remember those killed. and today s session of the air show has been canceled. understandably so. thank you so much, kristen dahlgren. vice president biden has generated a lot of talk after yesterday s meeting with
public. the council of air shows says while mid-air collisions do happen, accidents are rare. from the perspective of the crowd, of course it looks pretty dramatic. if you were actually along the same centerline at the airplanes you would see they are separated by a fair amount of space. so you can creating in the air show itself, somewhat of an illusion. you try to make the simple look spectacular, the difficult look great, and never try the impact, of course. that s an adage that many aerobatic pilots try to go by. it would become the site of one of the worst air show disasters ever. ten planes from the italian air force are part of an air show that has attracted 300,000 spectators.
