On April 28th, 2013 the Swiss Avro RJ100 "Jumbolino" (HB-IYT) took off at Airport Bern-Belp in Switzerland for a ferry flight to Zurich. Before that Swiss Air European Lines operated a charter flight from Barcelona to Bern-Belp on behalf of Edelweiss Air. The aircraft has two nicknames: "Jumbolino" due to its four jet engines like a B747 Jumbo Jet and "Whisperjet" because of its low level of operational noise.
