In February 2011, VistaJet commissioned RETNA to paint a Bombardier Global Express XRS, with the artist's signature calligraphy covering the aircraft's tail. The plane flew out of New York for the launch, then to London and Hong Kong, in what became known as the "Hallelujah World Tour." In May it was presented at EBACE in Geneva. Where a wall remains in one place, this work traveled at 40,000 feet, carrying the art across oceans. The project was realized with Thomas Flohr and Andy Valmorbida.
