It is estimated that the velocity of the meteor as it hit the atmosphere was roughly double that of an SRV (depending on whose data you use on the event).
My mind immediately went to the reactions of those Russian radar operators that had seconds to react to what must have looked like a warhead on trajectory for one of the most valuable military nuclear research targets of the last half century.
Regardless whether or not the Russian radars could actually track it, it might only have been its speed that kept something far worse from happening had hungover Russian radar operators had the time to make phone calls on what they might have seen on their screens, leaving hasty decisions up to other (potentially hungover) officers with both little time and little information on which to make a decision on response to what might have looked like an SRV on trajectory for a high-altitude airburst.
