"Looks like it's going to be a beautiful day." With those words the pilot who flew the Enola Gay, the plane that dropped the atomic bomb on Hiroshima, set off on his mission. The fallout from that act is explored in Al Smith's fascinatingly textured play, one of the most promising that I've seen on the Fringe.
There are many victims here, not just the 70,000 Japanese citizens who were vapourised or who died in the weeks that followed. There are other ghosts too: the place where the Enola Gay was built became a ghost town after the war when the aircraft industry collapsed. Smith entwines the story of the race to make the bomb with the personal tragedy of another Enola Gay, the granddaughter of the plane's designer.
The cramped Baby Belly venue does the rough-and-ready production no favours, and some of the performances from a largely student cast are uneven. But there is no doubting the power and passion or indeed ambition of this explosively topical hour.
