Our favorite paragraph:
And the DC-6 and DC-7 of today are vastly improved airplanes over what they were a few years ago. Creative maintenance at United's San Francisco base has virtually rebuilt them again and again. Minor flaws have been corrected and engine reliability has been greatly increased. Radar has been installed on all of them and the interiors of the DC-6s have been completely renovated. Altogether there have been over 2,700 modifications on the DC-6 and 1,400 on the DC-7 since their introduction.
These days, that would have been worded much differently. Would you want to fly in a plane treated to "creative maintenance?" We bet not.
