Final answer:
The first pronoun-related error in the paragraph is the use of 'their' instead of 'its' to refer to the creators of the Daedalus aircraft. The second pronoun-related error is the use of 'ahead' instead of 'a head' to describe the wind that caused the plane to ditch in the sea.
Step-by-step explanation:
The first pronoun-related error in the paragraph is the use of their instead of its to refer to the creators of the Daedalus aircraft. Since 'creators' is a singular noun, the correct pronoun to use is 'its'.
The second pronoun-related error is the use of 'ahead' instead of 'a head' to describe the wind that caused the plane to ditch in the sea. 'A head wind' is a common term used to describe wind blowing against the direction of travel.
