I wrote a new blog post on FAA's MOSAIC rulemaking, which covers the definition of light-sport aircraft. I think this is an important event for progressy people to study because it features:
1. FAA explicitly recognizing that "less safe is more safe" along some dimensions, and
2. It's an actual consequential rule that could drive a lot of progress in personal aviation in the coming years.
Jason has written before about safety being a key part of progress and the need for a philosophy of safety, and FAA is addressing these questions head on.
My mind was blown several times while reading the FAA's notice of proposed rulemaking, and I wanted to share the excitement with everyone else.
