Dash-8-ski. I have seen fans like this in the russian planes, but in one of our planes without an APU, there are fans to keep us cool during summer turn around's. Surprisingly effective, but seriously vintage! Thought it was kinda weird and funny. I also didn't really notice it being there till the captain pointed it out to me. Don't know whether i should admit that point however.
Anyway, all the best for the Christmas holidays, hope its been great with good family and food! Once again thanks for reading and the support!
