Speaking as an aeronautical engineer, I disagree.

> Engineering systems requires an engineering process and discipline, and agile is just not up to the rigor.

Agile just means closing as many feedback feedback loops as you can as early as you can, and to preserve opportunities to course-correct for as long as you can. All this to keep the destructive effects of surprises (which are sure to catch you) as low as possible.

This is good engineering practice, plain and simple.
