On November 6, 2015, when performing maintenance check for Boeing 777, reg. VN-A143, a team of three technical staff (Mr. Dao Van Duc, Le Van Thuan, Pham Trong Vi) working at VAECO's HAN Base Maintenance Center accidentally picked up a hand phone that had been left in the electric box of a business class seat. The hand phone is Nokia 8800e, Diamond Arte Version, Limited Edition with 112 real diamonds. A new one costs approximately 50,000USD.

After having reported to the Center's director, the mobile phone was handed to the Lost & Found Counter (NIAGS) in order to return to its owner. The three technical staffs will be praised and rewarded by VAECO's Trade Union.
