Synfuels are not a drop-in replacement. Jet-A has exacting standards, and it would be a serious chemistry challenge for synfuels to match Jet-A exactly. Most likely it would be possible but very costly. Most of that stuff is engineering superstition at this point. Most problems regarding hydrogen were solved decades ago. BMW actually made a LH2 powered car and had no big problems (except limited range). Frankly, you're just incredibly out of touch. We already are seeing H2 powered planes now, and a commercial jetliner powered by H2 should happen by 2030 or so. This very thread is about Airbus planning on building one.
