VIDEO footage of the aftermath of the 9/11 attacks which was filmed from space is to be broadcast in full for the first time on TV.
The footage, in which a huge plume of smoke is seen stretching from the site of the devastated World Trade Center towers, was captured from the International Space Station by astronaut Frank Culbertson.
Mr Culbertson discovered his friend was one of the pilots killed during the 2001 attacks when his plane was hijacked.
In the Channel 4 film, he is shown playing the Taps bugle call – which signals the end of the day for US military personnel – on a trumpet in tribute to his friend later that day.
C4's Live From Space season next week will feature documentaries about astronauts, building up to a live broadcast from Mission Control in Houston, Texas.
