Narrative:

While en route from hayward airport to rhv airport I was receiving flight following from bay approach on 135.40. I was doing approximately 160 KTS because I was in contact with bay and receiving radar services I was headed right for san jose's class 'C' airspace. I believe that right as I was entering class C bay says, 'radar service terminated, squawk VFR, frequency change approved.' I continued turning out of class C airspace and landed at rhv. I was a little annoyed at the controller because when one is in a fast moving aircraft, one cannot pull up to an abrupt halt to assess airspace and options, especially when doing 160 KTS. I may have inadvertently entered the class 'C' airspace while making my frequency change to rhv tower. On the other hand, I may have been just inside the class 'C' when bay gave me the handoff. I think I will take a bay approach tour over at oakland and see if I can't get to the bottom of what the correct response on my part should have been. Perhaps I should have not accepted the frequency change until I asked if I should continue through class C. However, when I have questioned busy controllers in the past on such matters, they have seemed very uptight and too busy to deal with queries.

Title: PLT OF A SMA TWIN BELIEVES THAT HE INADVERTENTLY ENTERED CLASS C AIRSPACE AFTER ATC RADAR SVC WAS TERMINATED.

Narrative: WHILE ENRTE FROM HAYWARD ARPT TO RHV ARPT I WAS RECEIVING FLT FOLLOWING FROM BAY APCH ON 135.40. I WAS DOING APPROX 160 KTS BECAUSE I WAS IN CONTACT WITH BAY AND RECEIVING RADAR SVCS I WAS HEADED RIGHT FOR SAN JOSE'S CLASS 'C' AIRSPACE. I BELIEVE THAT RIGHT AS I WAS ENTERING CLASS C BAY SAYS, 'RADAR SVC TERMINATED, SQUAWK VFR, FREQ CHANGE APPROVED.' I CONTINUED TURNING OUT OF CLASS C AIRSPACE AND LANDED AT RHV. I WAS A LITTLE ANNOYED AT THE CTLR BECAUSE WHEN ONE IS IN A FAST MOVING ACFT, ONE CANNOT PULL UP TO AN ABRUPT HALT TO ASSESS AIRSPACE AND OPTIONS, ESPECIALLY WHEN DOING 160 KTS. I MAY HAVE INADVERTENTLY ENTERED THE CLASS 'C' AIRSPACE WHILE MAKING MY FREQ CHANGE TO RHV TWR. ON THE OTHER HAND, I MAY HAVE BEEN JUST INSIDE THE CLASS 'C' WHEN BAY GAVE ME THE HDOF. I THINK I WILL TAKE A BAY APCH TOUR OVER AT OAKLAND AND SEE IF I CAN'T GET TO THE BOTTOM OF WHAT THE CORRECT RESPONSE ON MY PART SHOULD HAVE BEEN. PERHAPS I SHOULD HAVE NOT ACCEPTED THE FREQ CHANGE UNTIL I ASKED IF I SHOULD CONTINUE THROUGH CLASS C. HOWEVER, WHEN I HAVE QUESTIONED BUSY CTLRS IN THE PAST ON SUCH MATTERS, THEY HAVE SEEMED VERY UPTIGHT AND TOO BUSY TO DEAL WITH QUERIES.
