Large contrail left by a High Altitude/High Speed Recon Aircraft heading East maybe from CA/NV area.The contrail left by this craft was all that was visible. Probably a high altitude/high speed Recon aircraft. Its contrail is long and wide and definitely NOT a commercial plane. Cloud conditions permitting, the sightings are observed and recorded. The flight path this time was from West to East. This could be the government's replacement for the Aurora.
