cnn learning that the russian pilots did not go rogue, you say officials say the pilots were ordered to harass the drone by senior officials in russia s defense ministry, for now the fate of the drone wreckage remains unclear, the u.s. has no naval assets in the black sea that can readily retrieve it and the russians already reached the crash site and recovered some small pieces of debris but the u.s. took steps to wipe the drone s software, officials tell cnn making it highly unlikely that moscow will glean anything valuable from the remnants. we took met gating measures so we re confident that whatever was of value is no longer of value. we re learning tonight erin as well that the u.s. is conducting an assessment of its drone operations over the black sea. but we should note that does not include a complete more tore young man, apparently the u.s. flown another mission in the area with the same model of drone that previously collided with those russian jets.
