You don’t understand what a Test Engineer job is. As a Test Engineer you write tests to test a product as it is to be used in the manner the company states it doses. For instance my company states a new braking system on this car will stop the car is 6 feet. My job as a TE is to write up a test to put the car in the real world the car will be used it to see if it will stop in 6 feet. If the TE uncovers problems it is up to the company to correct them and then re-test till the car is stopping in 6 ft.
MS did not test the DC-6 in a real world test. They, both companies, assumed. I smile at the folks the justify this issue as being ok. My complain is not the product but the process. We users put money down on the belief we’d get a WORKING plane. We did not. No amount of pointing fingers changes that fact.
