During two days before the annual Vertical Aviation International (VAI) Verticon (formerly HAI Heli-Expo) trade show, which is taking place in Dallas, Texas this year, helicopters arrived on a temporary helipad before being towed into the Kay Bailey Hutchison Convention Center. Helicopters from manufacturers such as Sikorsky, Bell, Airbus Helicopters, Leonardo, Enstrom, Guimbal, and MD Helicopters are in attendance.
