Anyway Sextus, the arrows they fired were NOT light, they were pretty heavy and could come down with plenty of force. Parabolic fire was quite common with longbows. It was part of what made longbow training take so long. It wasn't just being able to put an arrow in a bullseye 20 yards away, and having the muscle developed to use the thing. It was also learning how to take long arching shots and adjust for wind, etc. THAT takes a lot of practice, even for landing it in a troop column.
