Back in 1969 a British Pathe News report told of elephants panicking and stampeding in Windsor Safari Park. Startled by noisy jumbo jets from nearby Heathrow Airport, they were running amok and hiding in the hedges.
A solution was speedily found to soothe the galloping giants: jumbo-sized ear protectors.
Calm was restored to the park when the elephants returned wearing made-to-measure giant ear defenders.
The elephant in the room is personal protective equipment and, in the historic case of the dumbo versus the jumbo, ensured this herd of elephants heard for many years to come.
