Extract from the book Past Tense posted
Flying the Atlantic in Sixteen Hours by Sir Arthur Whitten Brown;
AFTERMATH OF ARRIVAL
Alcock and I awoke to find ourselves in
a wonderland of seeming unreality the
product of violent change from utter isolation
during the long flight to unexpected contact with
crowds of people interested in us.
To begin with, getting up in the morning,
after a satisfactory sleep of nine hours, was
strange. In our eastward flight of two thousand
miles we had overtaken time, in less than
the period between one sunset and another, to
the extent of three and a half hours. Our physical
systems having accustomed themselves to
habits regulated by the clocks of Newfoundland,
we were reluctant to rise at 7 A. M. for sub-consciousness
suggested that it was but 3:30 A. M.
This difficulty of adjustment to the sudden
change in time lasted for several days. Probably
it will be experienced by all passengers
traveling on the rapid trans-ocean air services
of the future those who complete a westward
journey becoming early risers without effort,
those who land after an eastward flight becoming
unconsciously lazy in the mornings, until
the jolting effect of the dislocation wears off,
and habit has accustomed itself to the new conditions.
