Yikes, another issue with this plane...a kind of big one when an entire window panel blows out of the side of a plane. I know DH mentioned to me at the end of last year that Boeing asked airlines to inspect a bolt in the rudder, which seems kind of important. This just seems like one of those planes that has serious ongoing issues. I know the original issue was a big software problem that has been remedied. But loose bolts and window panels blowing out of the side of a plane seem like a big hardware issue. I was relieved to see that nobody died. DH only flies for work about 3-4 times a year, but always on this plane as they're a big part of the fleet for United. I wonder if other airlines will ground them for inspection temporarily?
