One interesting note is how this entire project has been 'in flight' for 30+ years almost cancelled with PAFI and then with then with recent pressure to close airports (namely KRHV) with leaded fuel as the lighting rod the FAA has now accelerated to “progress at the speed of light.”

"He added that the accelerated commitment reflects new urgency arising from the FAA’s awareness that some local governments are taking action to ban leaded avgas from being used at airports in their jurisdictions.

Local governments threats driving innovation at the federal level :P
