Well I have already flown on a ANA 787 before they were grounded from Japan to Hong Kong. Flight ok but that was before the well documented issues started. Would I fly one currently not if I had a choice as others have said. That said I do get to choose so no.
However I have been doing this flying bit for a number of years and have flown in any number of A/C and indeed airlines which had questionable records but I think the levels of safety have improved as have the a/c so the risk has lowered in my humble opinion. A/C that I have flown which had questionable records would be Electras - fires, DC-8 - Ground spoiler issues, DC-10 -stalls, a number of T tailed a/c before the stalls were under stood, the list could go on, however as I said they have improved.
