At 03:45 on the morning of April 30, Kissinger and Ford ordered Martin to evacuate only Americans from that point forward. Reluctantly, Martin announced that only Americans were to be flown out, due to worries that the North Vietnamese would soon take the city and the Ford administration's desire to announce the completion of the American evacuation. Ambassador Martin was ordered by President Ford to board the evacuation helicopter. The call sign of that helicopter was "Lady Ace 09", and the pilot carried direct orders from President Ford for Ambassador Martin to be on board. The pilot, Gerry Berry, had the orders written in grease-pencil on his kneepads. Ambassador Martin's wife, Dorothy, had already been evacuated by previous flights, and left behind her suitcase so a South Vietnamese woman might be able to squeeze on board with her.
