He was wearing his Swami cap

“He was wearing his Swami cap, which had two hanging straps, resembling an old aviator’s cap. As he entered the door, Prabhupäda reminded me of an intrepid aviator from a fighter plane with an open cockpit—a dashing figure. He looked rugged in the sense that he was ready to deal with the world and give his transcendental wisdom. Rugged handsomeness.” (Satsvarupa Dasa Gosvami)

Praying to join Srila Prabhupada on his sankirtana adventures wherever he flies. Kurma dasa.
