Some aircraft were in a specially convertible configuration, flying passengers by day and goods all night, but by 1999 the only one remaining in service, was a series 400 [G-BEYF] with Channel Express; it was retired at the end of March that year.

Cancellation

It is widely thought that the misjudgements made during the Herald project, necessitating major design changes so late in the design cycle, was to prove the company's fatal mistake.

Moreover, HP had been doggedly independent throughout its history.

The UK Government favoured placing orders for military and civilian aircraft with the newly nationalised aircraft constructors, combined under the name British Aircraft Corporation (BAC).

Sir Frederick Handley Page was very much against nationalisation.

Even after his death in 1962, the company continued to plough on as an independent constructor.

But this policy saw HP lose out to BAC in military and civilian orders by Government, with the notable exception of the HP Victor, which sold on its undoubted merit.

The demise of Handley Page was unfortunate.

The company made a series of catastrophic errors, not least of which was failing to judge the changing needs of the airlines that expressed early interest in the Herald.

The company did not have the stomach to press ahead in a difficult economic climate effectively competing with a much larger company.

Development of the Herald had proven to be an extremely expensive project.

Despite much hope over the Jetstream 137, and possible new variants of the Herald, with eight speculative builds at various stages of completion, Management made the difficult but brave decision to wind the company up.

Handley Page went into voluntary liquidation on the close of its books on 31 March 1970.

The profitable HP.137 Jetstream operation and drawing and design staff were the only useful parts of Handley Page left, but it was not enough for the company to survive as Handley Page.

The Jetstream operation was sold and transferred to Scottish Aviation, later to become a subsidiary called Jetstream Aviation.

This company was later acquired by and absorbed into British Aerospace.

The Jetstream went on to be a successful commuter airliner.

A belated attempt to revive the Herald design as a pure jet-powered development was shown in model form at the Farnborough Airshow in 1962.

The basic Herald components were incorporated along with a stretched fuselage, with two Rolls-Royce Spey turbo-fan engines slung in pods under the wings.

Other modifications included a shorter wingspan and revised tailplane mounted midway up the vertical tail. No interest was evoked in the "Jet Herald" with the project being stillborn.
