At first glance it seems
obvious that the stamp contains a non-map error, a plane without a
cockpit, no place for the pilot. In fact, the plane is an experimental
plane on which the cockpit windshield could be pulled down to reduce
wind resistance in flight, and the crew could collapse their seats and
lie down in flight. The cockpit in folded status is indicated by a
double break in a line along the fuselage. It looks like this — - — .
On May 13-15, 1938 the
plane with a crew of three, a pilot, co-pilot, and engineer
established a distance record of 7,235 miles during the three days and
a world speed record of 116 miles per hour over a 6,213.7 mile course.
The map in the background shows the Japanese islands
below the wing of the plane, with the Asian continent above. The stamp
was issued in 1939 as a part of set of 19 stamps.
A similar stamp was
issued as a provisional by the Miyako District in 1946 (Scott
Specialized. Ryukyu Islands 3X10).
