Report

Investigation Summary

On August 26, 1921, the SNETA Farman F.60 Goliath registration O-BLAN departed Croydon Airport at 12:25 for a routine mail flight to Brussels. At approximately 13:32, a gendarme on the French coast reported hearing an explosion and observing the aircraft's structure collapse before it fell into the sea. The investigation later attributed this to an in-flight fire. Witness Herbert Sullivan, aboard the yacht Zola, observed the crash and managed to recover a bag of mail. The tug-boat 'Champion' was the first vessel to reach the scene, followed by search efforts involving fishing boats and the steamship Tregenna, which spotted debris. Despite these efforts, the pilot and mechanic were never found. The aircraft was destroyed and lost in the Channel.

Final Conclusions

The investigation attributed the crash to an in-flight fire that led to a structural failure and loss of control. Both crew members, pilot Paul Delsenne and mechanic Raymond Rijckers, were lost at sea. The aircraft was a total loss.
