An aircraft transparency includes a first ply having a first major surface and a second major surface. A second ply is spaced from the first ply and has a third major surface and a fourth major surface. A polymeric interlayer is located between the first and second plies. At least one bore extends through the first and second plies and the interlayer. A high strength bushing is located in the bore, with an outer sidewall of the bushing in direct contact with the material of the first and second plies. In one embodiment, the bore is a tapered bore and the bushing has a tapered outer sidewall. In another embodiment, the bore is a cylindrical bore and the bushing has a cylindrical outer sidewall. 1. A hoop load bearing aircraft transparency , comprising:at least one polymeric ply;at least one bore extending through the at least one ply;a bushing located in the at least one bore and in direct contact with the at least one ply.2. The transparency of claim 1 , wherein the at least one polymeric ply comprises stretched acrylic.3. The transparency of claim 1 , wherein the at least one polymeric ply comprises a first stretched acrylic ply claim 1 , a second stretched acrylic ply spaced from the first ply claim 1 , and a polymeric interlayer between the first ply and the second ply.4. The transparency of claim 3 , wherein the first ply has a different thickness than the second ply.5. The transparency of claim 1 , wherein the bushing comprises a material selected from metal claim 1 , ceramic claim 1 , polymer claim 1 , and combinations thereof.6. The transparency of claim 1 , wherein the bore is a tapered bore and the bushing has a tapered outer sidewall.7. The transparency of claim 1 , wherein the bore is a cylindrical bore and the bushing has a cylindrical outer sidewall.8. The transparency of claim 6 , wherein the bushing has a taper angle in the range of 1° to 20°.9. A hoop load bearing aircraft transparency claim 6 , comprising:a first ply having a first major surface and ...
