The Sopwith Camel alone had a crash rate of 1:3 at first solo flights. Though it mainly wasnt fatal the number of dead by crash extends the downed Camel pilots - This however could proove that the agility of the Camel was quite defensive hence being a safe aircraft, when the pilot once had survived schooling and initial soloflights :-/
P.S. A trivia: Did you know that, during WWI, the british Royal Flying Corps suffered 6400 lethal casualties during pilot-training - while only 6200 british pilots were actually killed in combat...? Makes you think, doesn't it? [8)]
The 1:3 statistic did BTW cause the Camel to be designed in a two seater version to help teaching the pilots it's difficulties in the hand of an experienced instructor!
