the comparison would be interesting - even weighting for technology it would appear that the latter is racking up more incidents of significance (just a guess but I'd love to see the data).
Interesting though that the second LHR 'incident' echoes the first and again raises the issue of review, governance and oversight when critical functions are jobbed out. Single contract responsibility may be good for the P&L (and the statement of claim for that matter) but it is not always good for the product or your employees.
Slight diversion:
Also interesting that "informed anecdotal" suggests that both the a/c have a comparitively higher use of theraputic oxygen (ex bottles) in the cabin - as did OQA. Not enough data to make a determination but an interesting trend.
