That unfortunate Canadian couple whose "SOS" was overlooked last month got me to thinking: is stamping out an "SOS" a choice method for ground to air communication? It seems to be a common tactic in films and TV, yet I was taught that a large "X" or triangle was best, as these are quicker and easier to make.
