Monday March 25th. After morning job Hanna touched hangar with tail skid landing. Jolly close. Evening – flew to [Bertangles]. Hanna and I went in the [Bristol fighter]. Wandered round and eventually found the drome. Just landing when we saw a ridge. Opened throttle in hope of clearing. Hit ridge going full speed. Turned completely over. Was caught and pinned down by gun mounting. Hanna got out, and lifted tail when I crawled out. Hanna badly shaken, me ditto. Old cord breeches finished off. Leg torn a bit. Machine smashed. Fuselage broken behind Hanna’s seat. Nobody knew where we should be. All slept in empty huts on floor.
