what can we extrapolate from these flight tests? I've realized the first flights have been averaging about 4-5 hrs, one would assume the longer the first flight the less issues/ problems occurred and they were able to test majority of the systems. does shorter subsequent flight test indicate the same?
I don't think there is a general rule, at least not one that we know of. Not all flight tests have the same programme, duration is not 'until a problem is detected'. We do see some flight patterns being repeated, but I think there are too many variations to draw conclusions. We certainly would appreciate some insight.
