Black box recordings have demonstrated pilots incorrectly acknowledging Control Tower instructions that varied from their normal flight path daily patterns and routines
You remind me of the time I took a Cessna out of Cape Town International. The large commercial jet ahead of me (note:someway ahead) was sent his take off instructions. They were incorrectly read back, so the tower repeated them. They came back incorrectly again. After the third repeat the tower virtually said go and clear our airspace. Whether the aircraft reached its destination we'll never know.
