Couldn't infrared have been used to detect where the living humans were after the plane had crashed?
Sad outcome for the mother. :(

If they could afford to fly search planes overhead I can't see cost being the issue that prevented them from doing the search more efficiently.
It was not. The link you posted says that only film infrared was available then, and that would not be helpful for searching in a jungle.
And even in 1978 the best they could do was a resolution of 64x64 which isn't enough to identify a human from an animal.
