and then I remembered that 2 years ago in April 2017, I came across a seaplane with a kid in it, on top of a Rolls Royce

The model seaplane belonging to Mr Porter of Surrey, strapped to the roof of a Rolls Royce and on its way to the nearby lake, most likely Virginia Waters, a royal pleasure ground. April of 1930
