For things that aren’t what they seem, a biplane on a Manhattan rooftop is one of them.
Though Kaufman delights in onlookers wondering if a plane did indeed fly in and land on 77 Water Street, the aircraft is actually just an artistic re-imagining of a 1916 British Sopwith Camel, designed by Rudolph de Harak and constructed by sculptor William Tarr. It was hoisted into place by crane in 1969 and hasn’t moved since.
Art installations on a rooftop seem better than a helipad or air conditioning units.
