Black Triangle Sighting in Taylor, Pennsylvania on March 26th 2016 – a triangle that looked like an arrowhead

I was in my backyard, observing the constellation Leo with 10 x 50 binoculars even with them it wasn't big so it had to be up there pretty high. It came in my field of view, i thought it was a triangle it was shaped like a arrowhead. The lights were the same as stars. i only saw it for two seconds before i lost sight of it in the trees. I was just wondering what i saw maybe something the governments doing.
