Yes these are fine aircraft and you can add the Viscount, DC8 and many more.
But the point is this noise is so intrusive the likes I have never encountered from an APU. When it shuts down after the engine start, the noise from the Russian turboprobs is a mere whisper is comparison. I can't beleive a manufacturer can fit such a unit to an aircraft even if it was built some years ago.
Anyone know if its an aftermarket add on or have Antonov fitted some old Soyuz rocket motor from a scrap yard??? !!!
