Both planes had taken off from the same Moscow airport, within 40 minutes of each other.
They did crash at 1856 and 1859 (local time), only three minutes time difference.

A witness reports that one of the planes exploded in mid-air, and the other sent out a distress signal. (some reports say a hijack signal).
Experts suspects that Chechen terrorists may have caused the crashes.
