Yes, but they weren't making flights to Kenya or Hawaii.
To get from Honolulu to Kenya, they would have had to make five flights:
Honolulu-San Francisco
San Francisco-Chicago
Chicago-New York
New York-London
London-Nairobi
If you were lucky, you'd **maybe** get a 707 on the Chicago-New York and New York-London flight. The rest would be prop planes.
and you base this knowlege on....?
