Design of memorial for helicopter crash victims in Newfoundland unveiled

ST. JOHN'S, N.L. - A designer's concept for a memorial to the victims of two helicopter crashes in Newfoundland has been unveiled.

The proposal by artist Luben Boykov and landscape architect Frederick Hann includes a spiralling stainless steel sculpture that features the names of the 23 victims of both tragedies.

The sculpture is intended to represent the aerial screw prototype of the first rotary-type flying machine envisioned by Leonardo da Vinci in the late 15th century.

The memorial is a tribute to the six offshore oil workers who died when a Universal helicopter crashed on March 13, 1985, as well as the 17 people killed when Cougar Flight 491 crashed on March 12, 2009.

The memorial will be built at Quidi Vidi Lake in St. John's.
