This is precisely what they did do, as the MoD didn't think Russian forces would be stupid enough to directly engage the aircraft of a nation they're not at war with. RJ crew wear "Flanker Bait" patches on their arm for a reason, because they know they'd be the first thing to get hit if Russia suddenly changed its mind. Following this incident, they now fly with escorts. It was incredible luck that no lives were lost that day.

The RJ has no jamming capability. It is a SIGINT aircraft, not an EA platform. In areas deemed high threat, it would be escorted, and now is over the Black Sea, but previously the MoD didn't think Russia would actually be stupid enough to fire on a nation it isn't at war with.
