The flight continued to Milan's Malpensa airport after the plane's captain determined that it suffered no structural damage and two passengers who are physicians found no serious injuries, Giulio Buzzi, head of the pilots division at Neos Air, told Sky TG24 TV.
The ANSA news agency quoted bruised passenger Edoardo De Lucchi as saying meals were being served when suddenly there was "10 seconds of terror." He recounted how plates went flying and some passengers not wearing seatbelts bounced about.
Buzzi had said that the drop measured some 3,000 meters (10,000 feet) in a cloudless sky. But Milan daily's Corriere della Sera's web site, quoting Neos official Davide Martini, later reported that the plane first bounced up some 500 meters (1,650 feet), then dropped some 1,000 meters (3,300 feet) to some 500 meters (1,650 feet) below the original altitude.
