RJ85 Engines
SLF on an RJ85 yesterday.
I know there is an exhaust port at the bottom of the engines. During taxi you can normally see smoke exhausting from the port (I assume this is normal).
Yesterday I saw sparks within the smoke plume and there was liquid coming from the wing. The liquid was dripping behind the engine exhaust.
It had not rained all day. Take off and flight was normal.
Any ideas of the where the liquid could have come from?
