For the Russians it was a technical malfunction. The announcement was made by the British defense minister
A Russian fighter dropped a missile near a British plane patrolling international airspace over the Black Sea on 29 September. Defense Minister Ben Wallace told the GB Parliament, explaining that Britain suspended patrols following the incident and expressed its concerns to Russian Defense Minister Sergei Shoigu. The minister said that an “unarmed aircraft of the RAF RC-135 Rivet Joint” was “involved” by two Russian SU-27s, one of which “dropped a missile”.
Technical malfunction according to the Russians – Russia said it was a technical malfunction and subsequently Britain resumed patrols, but now they are escorted by fighter planes, Wallace said. The British defense secretary released a statement to parliament on Ukraine after returning from a visit to his US counterpart in Washington, Lloyd Austin.
British Defense Minister Ben Wallace, as reported by the Guardian, explained to the British Parliament that the UK temporarily suspended patrols following the incident and expressed its concerns to Russian Defense Minister Sergei Shoigu. Wallace said an “unarmed RAF RC-135 Rivet Joint aircraft” was “approached by two Russian SU-27s”, one of which “dropped a missile in the vicinity of the RAF Rivet Joint beyond sight range.” Russia said it was a technical malfunction, Wallace said. According to the British, however, the Russian version of the technical malfunction would be plausible.
“This is not a military escalation” – “We do not consider this a deliberate escalation on the part of the Russians, our analysis would agree that it was a malfunction,” Ben Wallace told the London House of Commons. “Minister Shoigu acknowledges that the accident took place in international airspace,” added Wallace, recalling that it is not the only plane crash involving Russian aircraft. A short time ago a NATO plane was approached by a Russian jet that almost touched it.
