an aero engineer commented to me once that the combination of bends in the centre spar had been thought to cause about twice the stresses in the centre section as originally calculated.
That could probably do with some elaboration from an aeronautical engineer
knowledgeable about stressing and the loadings that occur in different flight modes. Makes you wonder whether ATSB ever consult any real boffins?
re.. .. 'Healthy speculation' . . . . . aren't you being a bit harsh there on
Centaurus,
Prospector ?. Pre report speculation is often ludicrous, true, but post report, and in the analysis of deficiencies in reports. . . . it's a friggin' minefield, mate. Especially when the men sent out to do the forensic don't know a tapered spiggot from a knurled flange bracket.
