Hi,

The year in the title of this thread should be 1975, not 1970, as the NASA document dates these drawings from 1975.

Does anyone have drawings of Boeing helicopters similar to the ones in the NASA document published in 1976?

Vahe, you are posting crap posts.

In this case, the report is from 1970. Hesham's original posted date is correct, though sadly lacking otherwise in information. I found a (partial?) copy via the Wayback Machine:

The report is titled 'Study Of Aircraft In Intraurban Transportation Systems (San Francisco Bay Area)' by Boeing (Commercial Airplane Division)

Lockheed also did a report on this topic:
