This is not to level unfair accusations, but I do not know how to put four
adults in a 172SP and any reasonable amount of fuel without being
overweight
and aft loaded.

Um, I do. First of all, according to the FAA registry, N778LP is a 172S, not
SP. According to the 172S POH, the basic empty weight is 1650 pounds. Add 50
pounds or so for avionics, 318 pounds for full fuel (53 gallons), and
there's 540 pounds left for the two 18-year-old females (say, 125 pounds
each) and two older males (say, 145 pounds each). That's an entirely
plausible scenario, even in America.
