What happened August 1957 AD

His first flight in a rocket-powered aircraft was on August 15, 1957, in the Bell X-1B, to an altitude of 11.4 miles (18.3 km). On landing, the poorly designed nose landing gear failed, as had happened on about a dozen previous flights of the Bell X-1B.

On 26 August following intelligence gained by Colonel Godard's operatives, the 3e RPC raided a house in the Impasse Saint-Vincent where Yacef's new bomb-maker and deputy were believed to be hiding. After suffering several casualties trying to capture the two alive, both men were eventually killed.
