Explore 9/11

No information on whether or not the steel in the two structures shall have been able to sustain the impact of the aircraft in question... (Although prior arguments insist the jet fuel was burning hot enough to melt the beams, this is not valid as jet fuel burns at 1/2 that as it would take to melt steel.) Also, no information on World Trade Center building 7 which collapsed the same day (9/11/2001) while not having been hit by anything

But Where is info about WTC 7?

There is a bug I can not watch some videos then it will freeze

Great app to remember the victims of 9/11

There's some bugs in the videos, the app crashes.
