Clifton captured the 2nd plane impact and both “collapses” with his videocamera. Also, untelevised amateur Devin Clark and TV amateur Chris Hopewell caught all 3 events. Network cameras that did that include the CBS “Blue Angle” view, CNN 5 Penn Plaza (one of 2 cameras), NBC GE Bldg. (leaning cam), WPIX Metrocam, and NY1 ESB cam. The footage linked above comes from an interview on NBC 9/12 at 11:50 am.
