Two interesting daytime videos recorded last week in UK and California

Latest UFO sightings – I found two questionable but very interesting daytime UFO videos from last week and I really want to know your oppinion on this matter.

Saw this dark triangle object just hovering in the sky as I was on the way to a job, went to grab my camera but lost it behind buildings after about 2 minutes. UFO perhaps? This was last Friday around 1 :45pm driving on the Mancunaian way (A75) towards Salford, Manchester. Just want to know if there’s any explaination for this.

I filmed this on May 16, 2010 while we were driving our Jeep on the beach in Oceano, CA. I saw something out of place in the sky and pointed my camera at it. From there, it just looked like a weird cloud formation but after I saw the video, I could tell this was NOT a cloud. Could it be a blimp? And if so, what was it doing in Oceano? Did anyone else see this?
