Regarding flying an ILS on a VOR - I agree the track looks frighteningly matched, but as someone else has said, that does not require an FDR or CVR even to diagnose and will already be evident if it happened. I find it difficult to even contemplate as a possibility as it is 'un-charted'. We would have to be looking either a gross error by both crews - failure to brief, lack of cross-checks etc or a 'home-grown' procedure - maybe one of Rock's 'tend to push the envelope routinely', but surely with an ILS there................
Does not make sense.
All those considering 'pushing the envelope' DO remember that g/a performance is affected too by 'excessive' tailwind.
