An Israeli company is selling parachutes for people working in high-rise buildings in the aftermath of the suicide-hijacking attacks that toppled the World Trade Center.
"Within three weeks of the attack, the Executivechute was designed, tested, and ready to go," Anatoly Cohen, managing director of Apco Aviation, said on Thursday.
The backpack-type parachute, which is being marketed in the United States and Japan, has a $795 price tag and weighs two kilos (four pounds).
Its ripcord can be attached to heavy furniture or a special hook so that the parachute opens automatically after its wearer jumps out a window.
The military-style round canopy, as opposed to an aerobatic rectangular design, makes for a reliable but hard landing from a minimum height of 10 storeys.
