The last three posts from OP sound like they (French) picked up an unknown IR signature of something inbound from the air.. two 'targets' as indicated by splash zones 1 and 2. French seem to think that 'targets' might be Russian, or.. that the Russians would be able to confirm the signature of the 'targets'.

Well, now it looks like the infrared signatures are to due with the 'splash zones' 1&2. Floating living crystals.. might not be a recognizable IR sig, but would be something that you might subject to IR testing. The EM (Emeraude) does not carry any infrared equipment that is listed anywhere, so it is probably testing equipment as opposed to military visual/acquisition IR. Just a wag.. (wild ass guess)
