Narrative:

Began preflight at XA15 am. There was a big VFR hale around hayward at the time. At XA50 am I rolled for taxi. I departed the airport at XB00 am. I was intending to do a left downwind. On downwind it was getting foggy at 500'. I then crossed the airport over top to go where I thought it was clearer. At 700'-800' I was busting through a thin overcast. The hole that was there earlier had closed up and caught me by surprise. I continued my climb eastbound out of the area. On the hayward tower frequency I heard another plane doing an instrument approach. This reinforced in my mind that the field was IFR and that I should have gotten an IFR clearance for departure. Problem cause: hayward tower doesn't open until XB30 am so there is no ATIS. Oak ATIS was reporting 600' broken which I should have listened to before takeoff. I was also in a hurry. Two other planes went out ahead of me without getting an IFR clearance. They also busted the ceiling. I expected the hole over the airport to stay there when I took off but it had closed in. Future prevention: get an IFR to VFR on top clearance. Listen to oak ATIS for base information. Get a WX briefing. I hate breaking far's because it wrecks my mood the rest of the flight, which is unsafe. It also jeopardizes my license and my career.

Title: GA SMA VFR IN IMC. EARLY MORNING TKOF FROM HWD.

Narrative: BEGAN PREFLT AT XA15 AM. THERE WAS A BIG VFR HALE AROUND HAYWARD AT THE TIME. AT XA50 AM I ROLLED FOR TAXI. I DEPARTED THE ARPT AT XB00 AM. I WAS INTENDING TO DO A LEFT DOWNWIND. ON DOWNWIND IT WAS GETTING FOGGY AT 500'. I THEN CROSSED THE ARPT OVER TOP TO GO WHERE I THOUGHT IT WAS CLEARER. AT 700'-800' I WAS BUSTING THROUGH A THIN OVERCAST. THE HOLE THAT WAS THERE EARLIER HAD CLOSED UP AND CAUGHT ME BY SURPRISE. I CONTINUED MY CLIMB EBND OUT OF THE AREA. ON THE HAYWARD TWR FREQ I HEARD ANOTHER PLANE DOING AN INSTRUMENT APCH. THIS REINFORCED IN MY MIND THAT THE FIELD WAS IFR AND THAT I SHOULD HAVE GOTTEN AN IFR CLRNC FOR DEP. PROBLEM CAUSE: HAYWARD TWR DOESN'T OPEN UNTIL XB30 AM SO THERE IS NO ATIS. OAK ATIS WAS REPORTING 600' BROKEN WHICH I SHOULD HAVE LISTENED TO BEFORE TKOF. I WAS ALSO IN A HURRY. TWO OTHER PLANES WENT OUT AHEAD OF ME WITHOUT GETTING AN IFR CLRNC. THEY ALSO BUSTED THE CEILING. I EXPECTED THE HOLE OVER THE ARPT TO STAY THERE WHEN I TOOK OFF BUT IT HAD CLOSED IN. FUTURE PREVENTION: GET AN IFR TO VFR ON TOP CLRNC. LISTEN TO OAK ATIS FOR BASE INFO. GET A WX BRIEFING. I HATE BREAKING FAR'S BECAUSE IT WRECKS MY MOOD THE REST OF THE FLT, WHICH IS UNSAFE. IT ALSO JEOPARDIZES MY LICENSE AND MY CAREER.
