    Aquaman prevents his head from imploding when he dives deep because it is, in fact, filled with water and not a brain, as was previously thought. This allows him to equalize the pressure because he has holes in his ear drums. This explains why he spends his time with dolphins and tuna.

      As far as throwing the hammer and catching it to propel himself, it seems possible. Simple experiment, when bowling, throw the ball forward but don't let go, the moemntum you impart to the ball is sufficient to pull you forward. The question then becomes why do this, as it would be less efficient than jumping or if his legs aren't that strong, jumping with his hands? My guess is that his strength in throwing the hammer is provided by some patented technique that Thor had to license from the inventor, and a term of the license was that he couldn't use this strength to jump (presumably the license to do that would be more expensive), so he cheats the system by using a legal application (throwing the hammer) to accomplish the desired effect without technically violating his license. A clearly awesome hack that allows him to get the most of his money, to be sure. I am certain that since Thor's fragrant misuse of the "throwing" license, the inventor has since revised future license agreement to prevent its misuse.

      As far as his helmet falling off, he just needs to keep his feed pointed roughly in the direction of motion, no biggie.

      As to lightning flashes, I lack sufficient knowledge to make any thoroughly accurate claim, but my guess would be that before he goes to use this power he rubs his feet on some carpet a *lot* before heading out, thereby giving himself a lot of static electricity.

So Superman counters by using a giant flying television to Super-Hypnotise everyone to disbelieve any illusions / see what's really in front of their eyes.

    Superman spent most of the rest of the comic making excuses as to why he is pretending to be Clark Kent, and covering for where the "real" Clark Kent is, since no one believes his disguise any more.

    After the bad guy is caught and Superman un-hypnotises everyone, the comic ends with CK getting an artist to sketch his face.
