The Piasecki PA-97 Helistat was an American experimental heavy-lift aircraft, built by Piasecki by fastening four H-34J helicopters to a framework beneath a helium-inflated blimp envelope. The sole prototype was destroyed during a test flight, killing a test pilot and injuring another four in the course of a single incident in 1986.

"No, you don't understand, this incredibly dangerous and unreliable experimental vehicle that can't even survive a single test flight wasn't designed for regular flights, it was designed to fly in some of the most dangerous flying conditions possible."
