&gt;Why not? The reason you&#x27;re not allowed to get on the highway with a scooter or a bike is because it&#x27;s dangerous to others. The only danger to me taking my airplane across the Atlantic is to me.<p>Quite a lot of aviation regulations are designed to protect people from killing themselves and their passengers. For example, the requirements for carrying lifejackets&#x2F;rafts, survival gear, etc. depending on where you&#x27;re flying.<p>Also, as pointed out in other comments, there are requirements  for flying this route (IFR, HF radio, liferafts, etc.), which are probably sufficient to protect pilots from themselves. Yet, even if you follow all the rules and wear a survival suit (which I don&#x27;t think is required), it&#x27;s still a highly risky endeavour.
