Do you often ponder the potential safety implications of today's reality? How fatigue, internal and external stressors etc. can affect the margins?
Parts of the general public don't seem to appreciate it much when some pilots and others express their worries. They seem to assume that current regulations are adequate, and thus there is nothing to worry about. The fact that humans form an essential and vulnerable part of a larger and imperfect system seems to go right over their heads.
