I recall these 720-062 from Pacific Northern.
When layoff 1974, PanAm helped to get me with AeroAmerica.
Was a BFI Boeing Field operator with 707/720. Base also TXL West Berlin.
These two 720-062 were "spare parts" for AeroAmerica planes in BFI.
Stole a "720" control wheel emblem (souvenir) from one of their cockpits...!
