EW loco,
Sorry to burst your bubble but all from EWI through to EWS had probs,some minor some major (three weeks in the shed having APU,both packs and all plumbing removed and cleaned,all the carpets,seats and galleys removed etc.etc)It wasn't pretty !!
Plane speaker,
It has been the best o/time generator ever built. As to aussies having good noses,ta. In your operations do you now use Mobil 291 as opposed to 2.(For the uninformed it has the same quality's with-out the aromatics,sort of like taking the onion smell out gas so no-one can detect it and/or grizzle with a possible law suit to follow).
