1934 cover with U.S. and Polish franking, special cachet and signed by both Adamowicz brothers, faint toning, otherwise v.f. On June 28, Benjamin and Joseph Adamowicz took off from Floyd Bennett Field in NYC and landed in Harbour Grace, Newfoundland. The next day, they took off from there for a Trans-Atlantic trip. Through mechanical problems, leaking engine and heavy rainstorm, they managed to reach Europe (near Caen in France). The next day, after repairing a landing gear, they took off to Paris, then to Germany, where they were forced to land due to fuel leaks. On July 2, the brothers arrived in Warsaw, Poland, treated as heroes. The Adamowicz brothers were possibly the first amateur pilots in the world to fly a plane across the Atlantic (Image)
