> This is the first time we had a failure on the vehicle’s parachute system. Doesn't this mean that neither Matternet nor the Swiss Post tested the failure modes of this drone enough? If it never happened before, they didn't test it enough to get any estimate for a MTBF for this particular part. But this is to be expected from the Swiss Post, they do sloppy work and blame others, just read their dementi: >As such, we have asked Matternet to implement various urgent measures: >[...]The shrill whistle, which alerts people near the drone when it is making an emergency landing, will be made louder. The whistle couldn't be heard in that accident... Sound like somebody didn't test a single emergency landing in that forest and asked the numerous strollers whether they have heard anything
