Beware:
(...)and discovers the human stories of the people who spend their life in flight(...)
It sounds like one of those series where: Capt Horatio Sky-god relaxes by taking his Jack Russell Zeus, for a walk when not flying SLF to exotic destinations throughout the globe occupies; say 50% of the transmission time; to broaden the interest base for the viewers
.
Some might say that's entirely laudable, but there comes a time when the presentation of the exciting world of aviation becomes diluted by the needs of the producers to produce "product". Ok that's probably unfair as the series has not jet been broadcast, but by previous experience, for me at least, real communication of the excitement of the various professions has not been good.
