ABSTRACT	The first flight test of the Japanese SPF project will be held in the summer of 2003. Direct measurements and sampling of atmospheric gas in the stratosphere will be conducted for mission experiments. In addition to the launch operation, there was also concern about the issues of the recovery operation, retrieving the gas bottle pack and the floating of the airship hull on the sea. Before the flight test, a retrieval test was conducted using a 45-meter long airship off the coast of Port Hitachi. The main purpose of the test was to experience the recovery stage of the flight test and evaluate the retrieval procedure. The pressurized test hull fixed on the ship sailed from the port and was released off the coast. When it ascended to 70 meters, a detonation code on its back tore the envelope and the envelope fell to the sea. A diver removed the gas pack from the envelope and retrieved it. The wet envelope was very heavy and it was hard work getting the bag back onto the deck.
