Yup, actually I have, quite a bit* and would again.
I should declare an interest I guess, although not a Boeing employee, I lived and breathed this airplane from 2005 to 2011. Along the way I've met and worked with a lot of the folk who designed it and a lot of the folk who build it. Almost without exception they were great people and there was not one who was unaware that one day their family members would fly on it.
Sure it has issues, and don't get me started on the 'MBAs running engineering' thing, but I suspect do most new airplanes do. So until I hear some facts as opposed to speculation on these last two events, (and please, what is so unusual about an air turn-back?) then I would happily scamper on board a 787 tomorrow.
*a while back, so the interior finish wasn't quite so good as now - although it was a tasteful shade of green, the seats were wider with neat full-harness belts and they provided loads of instruments for great in-flight entertainment!
