Scrabble?! MULTIPLANT

Definitions of MULTIPLANT in various dictionaries:

In aviation, a multiplane is a fixed-wing aircraft-configuration featuring multiple wing planes. The wing planes may be stacked one above another, or one behind another, or both in combination. Types having a small number of planes have specific names and are not usually described as multiplanes: Biplane - two wings stacked one above the other Triplane - three wings stacked one above another Quadruplane- four stacked wings Tandem wing - two main planes, one behind the other. The tandem triple or tandem triplet configuration has three lifting surfaces one behind another.While triplane, quadruplane and tandem designs are relatively uncommon, aircraft with more than four sets of wings rarely occur - none have proven successful.
