Last I heard, there were a couple still flying in China.

Basically, the aircraft was underpowered, and that restricted routes and
payload. The Spey engines couldn't be upthrusted, and various methods
were used to squeeze extra thrust (water ingestion I think, and an
auxiliary boost engine, the RB162. The 162 was a odd engine, but that's
another story.) With this and against Boeing muscle, HS hadn't a chance
