Aerandir?
In the middle of A-IR we have an ER[R]AND, which can be a mission to summon help.
Aerandir was, in turn, one of Earendil's companions on the mission to summon the help of the Valar. They made the journey in Earendil's ship, which was soon to become the airborne spectacle of the morning star.
I have a feeling I am way off; if so, I demand extra points for a creative answer.
