fly by the seat of one's pants
Wing it entirely
To fly by the seat of one's pants is to proceed by instinct and improvisation rather than planning or established procedure.
The phrase originated in early aviation, when pilots lacking instruments relied on physical sensation—feeling the aircraft's movement through the seat.
Now it describes any situation handled through guesswork and quick adaptation: We didn't have a manual, so we flew by the seat of our pants.
The implication is usually that things worked out despite the lack of preparation.
