After the October Revolution he managed to return to Warsaw and in November 1918 Idzikowski joined the newly-born Polish Army, in the rank of podporucznik pilot (flying 2nd Lieutenant).

A French attempt had been made in May 1927 aboard The White Bird (L'Oiseau Blanc), but the aircraft disappeared over the Atlantic.

After considerable hesitation, the Polish authorities, urged on by the press, eventually succumbed and bought a special plane for a transatlantic flight from France.

After 31 hours of flight, oil depleted, Idzikowski decided to land on water by the German merchant ship Samos, about 70 km from the Spanish coast.

However, because of more irregular engine work, at 9 p.m. (7 p.m. local time), Idzikowski decided to make an emergency landing on a closer rocky island Graciosa.

In the crash, Ludwik Idzikowski was killed, while Kazimierz Kubala was saved by a farmer from a nearby village who pulled him from the wreckage.

Idzikowski's body was returned to Poland by the sailing ship ORP Iskra and buried with honours on August 17, 1929.
