In May 1973, during a NATO exercise in Italy, Pappas refused to sail the boat back to Greece and anchored off Fiumicino, Rome, where he held a press conference denouncing the military regime.

Pappas was expelled from the Navy and stripped of his Greek citizenship by the junta for his action; he remained in Italy as a political refugee, along with his crew members, to return to Greece and the Navy only after the regime's collapse in 1974.
He later reached the rank of Vice Admiral, and served as Chief of the Navy General Staff from 1982 to 1986. "Velos" is now a floating museum themed on the anti-junta struggle, anchored at Faliro Bay.
