CNN has a minisite to commemorate the 15th anniversary of 9/11. The footage on the site is taken from the infamous Naudet brothers documentary which remains the only actual video footage of the first plane hitting the Twin Towers on record.
In 15 years, I have never seen the full Naudet brothers documentary, only clips of it like the ones shown on the CNN minisite. I think today, I will finally watch the full thing. Just like re-living the news broadcasts every year, this is how I come to terms with this tremendous loss.
