Harrier reliability
In 14 years at Dunsfold, never knew a 'modern' Harrier to have an actual engine failure, except the rare fingers & thumbs swithchology snag & maybe pop surges in the hover ( recovered by Test Pilots without much effort or brown trousers )- I presume it wouldn't be nodding to Her Majesty, though that would be a nice idea & fitting salute.
Both Art Nalls & primarlily John Farley among others have glided them rather well - though starting off at 2,000 feet seems a bit challlenging !
As for Health & Safety, as Tim Brooke-Taylor once mentioned, " as long as you've got your elf !"
