Ex-CEO of ICON Aircraft dies in Switzerland: extreme wingsuit flight ends tragically.

According to The Sun: Kirk Hawkins, 58, was described as the 'most incredible person' by his bewildered friend, as tributes poured in for the former U.S. Air Force pilot.

Kirk jumped from a helicopter along with three others near the summit of the Eiger.

They descended along the eastern ridge before the American CEO of ICON Aircraft struck some trees just west of Schusselaundungraben.

He died after hitting the ground, confirmed police.

His close friend and business partner Stein Strammt announced his passing with a hand.

He wrote: 'Kirk was the most incredible person I ever knew or will ever know.'

'Kirk delved into life activities that most of us would never touch.'

'He was quite good at risk assessment, probably because he took so many.'

'He could get you into tough situations, but he was also the one you wanted beside you in a difficult moment.'

'I imagine Kirk, in his last moments, would know what was coming, think this line, and laugh one last time before the exit.'

Kirk and Stein founded Icon Aircraft when they created the A5 light sport aircraft with amphibious features in 2006.

Kirk had master's degrees in engineering and business, which he earned at Stanford, that helped him invent the floating aircraft.

It was considered an innovative aircraft upon its debut, but it had a high price tag of about $389,000.

Deliveries began in 2016, but less than a year later, a fatal accident occurred.

Former baseball player Roy 'Doc' Holladay died at age 40 in a plane crash.

When he landed in the Gulf of Mexico near Florida.

Kirk remained as CEO for another 12 months after the fatal accident before leaving the company in November 2018.
