We don´t recommend wearing this product next to spinning props, jet intakes or whilst lying on the active runway! We do recommend showing it off mercilessly, as, after all, you have a passion for aviation and know about wing loading, weather fronts, MTOW, and QNH.
Do follow these care instructions, which are also printed onto the inside label of the T-shirt but are detailed here should you wish to cut the label out. Your garment will last longer washed at 30 degrees and your washing machine will use less energy. It is best to iron the garment inside out.
