- Danny still remembers the day ______ he first flew an aircraft.
Question 1:
Danny still remembers the day ______ he first flew an aircraft. A. on when
B. that
C. which
D. on which
Feedback It is correct to say 'on which'. This structure is quite formal, so we could use here a relative adverb 'when'.
