Maintenance problems plague the 918th. General Creighton from G-2 orders the 918th on a mission to drop a spy (Ilka Zradna) into occupied Poland. Aircraft Army 262 has to abort the mission, (Langaard & Hetz are killed) and only 3 crew (Komansky, Rodman, Booker) survive along with Ilka. Back at Group a furious Komansky slugs Podesta and both are busted to Private by Gallagher. General. Creighton informs Gallagher that 20 German saboteurs are known to be in England impersonating Allied airmen and they will be closing in once they can identify the entire Group and the leader. Podesta is later found murdered beside some sabotaged ammunition and it is learned that the saboteurs are on base. It turns out that Podesta was a CIC agent (as is T/4 Thibideaux). General. Creighton orders CIC Major Adams on base disguised as Master Sergeant Young. Gallagher orders a plane on the mission to drop Ilka. He then switches to the Piccadilly Lilly. Just before they take off, T/4 Hansen delivers coffee to the crew, which turns out to be a bomb. Defused in time by Gallagher. It turns out that the Polish Liaison Officer, Captain Zoller; a guard, T/4 Hansen; & a mechanic T/4 Pierson are the saboteurs.
