No the 787 if allowed to fly should be Non ETOPS to gather more data
To gather relevant data this time (contrary to the test standards obviously not able to duplicate the issue and real in-service conditions), the 787 should be operated as it is intended to do, as a point-to-point long range aircraft connecting totally different climate zones. Gatering data with limited operation is no real data. So there is a catch 22... If we operate as intended and have another failure, this is dangerous. If we operate with limitations and have no failure, it does not tell us how the aircraft would behave in real operation, so this is dangerous as well once we clear the aircraft to operate unlimited.
