Who is king comparing to a flight's ground crew in this metaphor from his nobel prize acceptance speech?

Hi there!

The answer you are looking for is The people who have worked hard to make the Civil Rights movement happen but will never be given an award.

In this excerpt from Martin Luther King’s Novel Prize acceptance speech:

“Every time I take a flight, I am always mindful of the many people who make a successful journey possible the known pilots and the unknown ground crew… You honour the ground crew without whose labour and sacrifices the jet flights to freedom could never have left the earth.”

Mr King compares the people who have worked hard to make the Civil Rights movement happen but will never be given an award, to a flight's ground crew in this metaphor.

Hope this helps!
