Aren't engine covers free?
I notice photos in the media of grounded airplanes in Europe with improvised coverings on the engines, made of plastic and tape, apparently.
Don't you get a free engine cover when you buy a jet engine? I've always assumed that all those bright red REMOVE BEFORE FLIGHT covers that fit so nicely over the engines and other open bits were supplied as free accessories by the manufacturers of whatever the covers are covering. Isn't this the case? Do you actually have to buy them separately?
On a related note, are the covers kept in the aircraft or on the ground?
