For my contemporaries, Sorsogon Pilot Elementary School (SPES) is simply known as the Pilot school. As far as I know, this is the only pilot school i’ve heard in Sorsogon; though, in some provinces I went to, pilot school can also be heard about normally on bigger towns.
I am really curious if the name has been that way ever since. It’s not. It was actually known as Sorsogon Demonstration Center¹.
