Inertia slows the airplane and pulls it down.

The force from throwing the airplane loses strength as the airplane moves.

Answer 1

"The unbalanced forces of air resistance and gravity slow the airplane and pull it down."

Gravity constantly pulls the plane downward, and air resistance (plus insufficient lift) produces a net unbalanced force downward, so the plane decelerates forward and eventually descends.
