Mike B,
As
Paxboy said, no, it doesn't.
I flew a 744 last night but would have been equally happy in aTripler.
Indeed I think Paxboy has it slightly wrong, IIRC this might end up being the first 777 hull loss since the type's introduction - so that's about 13-14 years.
Yes there might be a problem which will come out in the wash and which will make 777s and 787s even safer, but they've worked pretty darn well to date.
You seem to forget that the drivers and bikky-chuckers who work on them every day, also have families they want to see again and generally do not come to work with a death wish - if they are happy to climb aboard, so am I, and so should you be.
Please leave the scaremongering to the Daily Mail and its ilk.
