Early biros were used in the RAF primarily because they provided a reliable writing instrument that performed well at high altitudes and in various weather conditions. Unlike fountain pens, which could leak or freeze in cold temperatures, biros utilized a ballpoint mechanism that prevented ink from flowing uncontrollably. This made them practical for pilots and personnel who needed to write in challenging environments without the risk of damaging important documents. Additionally, their portability and ease of use contributed to their adoption in military settings.
