Smoker
I know this is slightly deviating from the noise issue of this thread, but what about the ol Antanov An-12 that used to carry seafood out of Bris to Honiara ?? She wasn't noisy, but sure did leave a beautiful smoke contrail in the sky after departure. I remember a few times travelling to the airport for work and not even seeing the plane, but its 4 lines of brown vapour streaking across the sky gave it away that she was airborne !!!
Perhaps Ruddy got sick of the particles of grime landing on his place at Gordon Park ??
