Whisper Jet Inc. was established in 1993 by Mr. Elling Halvorson. Back then, Elling's dream was to create the world's quietest, medium sized helicopter while improving its high altitude performance. His aircraft of choice to develop Quiet Technology (QT) was the Sikorsky-S55. The aircraft had a very roomy interior and was built to a standard of strength not available in present day helicopters. He purchased around 75 airworthy and non-airworthy airframes from various operators around the world. He then purchased massive new and used serviceable spare parts inventory, over 15,000 line items including new blades, fuselage skins, rotor heads, tail rotor components and flight controls etc.
