Thanks for the schedule, Travis, we wait with baited breath...

Adding people to the design and review process will help avoid oversights, especially multiple ones.

It is a double edge sword - sometimes multiple reviews and committee designed dilutes ownership, and no one digs into the details, everyone figuring someone else already had done their homework.
A few years ago my son was hired as a Summer intern to work with a high pressure system (~20k psi) that I had both designed and assembled. I took a long, long look at the plumbing, the electronics, the tubing guides, valves, shielding, etc.
But I didn't catch everything - there was a bleed off path from a high pressure line through a supply valve in the low farm, and it popped a burst disk. Would more reviews have caught this failure mode? Maybe. A better engineer would not have created the potential. (No one was hurt, but it scared the hell out of him when the disk burst and vented...)
