Don't know what's in the second photo, but that first one reminds me of a craft known as "pumpkin seed". The shape and the trail it's leaving there are reminiscent of a craft that's been seen flying over the Californian coastline on numerous occasions heading towards Edwards AFB, and also in the direction of Nevada, towards Area 51. If it is indeed "pumpkin seed", it's of Earthly origin. They believe the craft is a triangular shaped craft that uses a liquid hydrogen injected methane pulse detonation drive system for propulsion. The contrail it leaves in orange in colour and on closer inspection looks like what you see there.
