More on the Madrid fire
I wasn't able to transcribe and translate the video from Barcepundit, but he's linked to this article

On the tape, which was aired by Spanish television stations on Friday night, two figures in silhouette are seen inside the blazing Windsor Tower more than two hours after the building was supposedly evacuated.

The figures appear to be moving about eight floors below the core of the gigantic fire, according to Carlos Just, a lawyer who took the amateur video from a building about 200m away from the tower at around 3:00 am (02:00 GMT) last Sunday.

Just called the emergency services who said at first that the figures were firefighters. But an evacuation of the fire crews had been ordered earlier for fear that the building might collapse,

Madrid's mayor has called for an investigation to find out if anyone was inside the 106m building when the fire broke out. No dead or missing have been reported.

Officials last week said they believed the office tower was vacant as it was a weekend night. Some speculated that the silhouettes could have been an optical illusion.

No optical illusion lasts that long.

The authorities should be able to verify the time of the phone call to the emergency services. As Barcepundit said,

The images were taken between 3 and 6 am, and the really suspicious thing is that the fire department has officially declared that at 1 am -that is, two hours before the first images were taped- all firemen had evacuated the building because they saw that there was nothing they could to to put it out.

At that point, the fire was raging in full force.
