According to Lockheed testimony, the production phase was to run from the end of 1971 to
the end of 1977 with about 210 Tri Stars as the planned output. At that production rate, the
intensive production costs would be relatively front-loaded, so that the $490 million ($14
million per plane, 35 planes per year) annual production costs could be assumed to occur in
six equal increments at the end of years 1971 through 1976 (t=4 through t=9).
