The company operates planes on

schedules over the 1 04-mile air
way between Seattle, Medford and
Kan Dietio, carrying mall, passen
gers and express from one term
inal to the other In twelve and
three-quarters hours.
Hall said that the route was
started four years ago as an air
mail line, and planes powered with
90 horsepower engines were used.
The airway was undeveloped, and
the first lights fur night flying
were installed drover Tyhr uiui

In IflliS the company was taken

The airway haH been completely
lighted for night flying by the de

lu-inlle intervals and lighted
emergency landing fields estab

ports. , The newest Improvement on the
Jtacific Air Transport route, ac
cording to Hall, is the installation
of the two-way radio telephone
communication system between
the ji In iuh in flight and operators
at eight ground statlor.a located
on the line. One of these pow

upon visioning the importance of air transportation and providing an out
standing and adequate airport. Tomorrow sees the dedication of a finished
airport which would be a credit to a great metropolis.
A splendid airport, a splendid service with Boeing planes and pilots, whose
average flying time is 4500 hours, give Medford a favored place on the air
map.
