― Harold, A New View for Thomas

Harold is a cream helicopter who patrols the skies of Island of Sodor, searching for emergencies.

Technical Details

Basis

Harold is based on the Westland Whirlwind helicopter with added pontoons. These helicopters were built by Westland Aircraft in the United Kingdom as license-built versions of the Sikorsky S-55 helicopter (also known as Sikorsky H-19 Chickasaw), which originated in the United States. The Whirlwinds were primarily used by the Royal Navy's Fleet Air Arm in anti-submarine and search and rescue roles, the latter of which was the inspiration for Harold. Around 70 of these helicopters still survive in some form.
