Title: Human Problems in Jet Air Transportation
text: THE human problem with jet aircraft begins even before take-off, the author points out, with discomfort and loss of efficiency from noise, and ground injuries on the field or in repair shops. In the air, although noise and vibration in the jet plane are less than with the reciprocating engine, human tolerance is matched against other extreme forces of acceleration, direction changes, temperature and pressure variations. Through detailed examination of what happens to passengers and crew in the many situations that can arise to challenge human limitations, the author shows why he believes there is need for closer cooperation between the biologist and the engineer, and for better education of crewmen in the effective use of their equipment and in their own physical limitations.
