SMITHTOWN - Two weeks in Smithtown ended with a harrowing experience for some exchange students who were aboard the Air France Airbus that collided with a Delta jetliner at John F. Kennedy International Airport last night.No injuries were reported after the huge Air France A380, the largest passenger jet in the world, clipped the smaller commuter plane and spun it a full 90 degrees before coming to a halt at 8:15 p.m. The Air France jet was bound for Paris with nearly 400 passengers on board, among them a group of 18 French exchange students returning home from a two-week stay in Smithtown."The students were really scared when the plane hit the plane from Delta Airlines," says chaperone Hassan Elamiri.Last year, students from the same exchange program couldn't return home because their flight was canceled due to the volcanic eruption in Iceland that tied up European air traffic for weeks.The National Transportation Safety Board says it'll examine the steps taken by the pilots aboard the two planes and controllers' instructions.For an interview with chaperone Hassan Elamiri, go to your digital cable box and select iO Extra on Ch. 612.
