Indeed, Russia dispatched a pair of Su-27 fighter aircraft to intercept the MQ-9 Reaper.
It is believed that Russian forces dispatched from Crimea recovered most, if not all, the wreckage, including the top-secret intelligence pod that had been mounted under the left wing of the aircraft. If this is the case, critical US intelligence collection capabilities would have been compromised, allowing Russia to better protect itself from sensors like the one carried onboard the downed MQ-9 Reaper aircraft.

I hope the "top-secret intelligence pod" is just a cache of Hunter Biden, Anthony Winer and Seth Rich laptops.
