Swiss Air-Rescue Rega took delivery of its third Bombardier Challenger 650 on December 17, Bombardier Business Aircraft said. The acceptance of the large business jet completes an update of Rega’s fleet this year from Challenger 604s.

Rega is a non-profit foundation specializing in aeromedical evacuation. Each of its Challenger 650s is equipped with two intensive care units and the aircraft are used to repatriate patients from abroad. Rega also operates a fleet of 17 helicopters.

“It is with the utmost confidence and pride that we deliver a third Challenger 650 to our partners at Rega,” said David Coleal, Bombardier Business Aircraft president. “Confidence because we know these aircraft have the reliability that is so important when lives are on the line, and pride to see the Challenger platform configured into the world’s most advanced air ambulance.”

Bombardier said Rega acquired its first Challenger in 1982 and has been a customer ever since.
