Oval craft seen passing in front of moon

I was remarking to my wife last night how amazing the moon looked.  It was about 3/4 full but very crisp and clear in the sky.  It was overcast around the moon and as I was looking at the moon an off white oval looking craft was flying faster than airplane.  I was curious because there were no con trials behind the craft.  I have seen satellites at night and this craft was traveling about as fast.  I watched it as it approached the clouds that were pretty high in elevation and the craft went behind them.  The cloud cover went as far as I could see so I did not see the craft after going behind the clouds.  The craft did change to a darker shade just before going behind the clouds so I though maybe it was going into the earth's shadow.  I certainly can say it was not the shape of any aircraft I have seen and that is why I am reporting it.  I pointed it out to my wife but she didn't see it.
