Hybrids are stepping stones along the way to full electrification. They reduce emissions somewhat. We may see hybrids be commercialized for small planes in 10 years, for large planes in 20 years. etc. etc. What I'm saying is that I don't see these technologies allowing supersonic speeds, meaning supersonic=fossil.
