i was reding this reddit thread and they suggested that most crashes were caused by pilots being distrated by animals or other things and crashing into each other, is this true?
A survey of causes of death in British pilots found that 58% died from enemy action while 42% died in operational mishaps including training in the first year of the war.
Although some of the crashes are going to be due to distraction and error, there will be others due to mechanical failures and bad weather.
Also, I think that the post you link to is making a joke about dogs in the movie UP.
