The Boomer is a paper airlplane that usualy glides smoothly and does not change height until the end(the landing). Your wingspans have to be almost perfectly symmetrical for it to fly straight and not curve(not change direction). When you throw it, you can hold it anywhere on the bottom except for the very back of the bottom, don't try to throw it hard, just put it forth and genty let go. It does have a little speed, but its made for soaring in the air.
The Explorer
The Explorer is a paper airplane that glides fast then soars near the end when it flies, so it can really be put into two different sections (Gliding and Speedy). We decided to put it into the gliding section because even thogh it is going fast, it is still mostly gliding. When you throw it, you have to hold it near the front and throw at a medium hight with high pressure.
