Narrative:

My captain and I were in the middle of our workday of flying air tours over the grand canyon. Flight dispatch released us empty to the grand canyon in order to retrieve some passenger. We received the standard clearance from las vegas ATC and flew it uneventfully from the airport to the boulder city VOR. Once over the VOR, our typical release point from departure control, my captain told me to go ahead and sign-off with ATC. ATC went ahead and told us to squawk 1200. At the time we were level at 5500 ft. As soon as we were released he started a near maximum performance climb which isn't done, especially in an empty aircraft, at this point because there are still ledges of the class B airspace overhead. Since I wasn't sure of their altitudes, I got my charts out and quickly researched. By the time I found the information we were already back in the class B. I showed the captain the chart, which he looked at with initial suspicion, but then he pushed the nose over so as to avoid the last ledge. Nothing ever came of the airspace breach. This captain is one of those from the old school who doesn't put much stock in younger pilots in the right seat. I shouldn't have let that stop me from questioning him strongly before I looked at the chart.

Title: GRAND CANYON AIR TOUR OPERATOR, UPON RELEASE FROM TRACON, CLBED BACK INTO CLASS B AIRSPACE.

Narrative: MY CAPT AND I WERE IN THE MIDDLE OF OUR WORKDAY OF FLYING AIR TOURS OVER THE GRAND CANYON. FLT DISPATCH RELEASED US EMPTY TO THE GRAND CANYON IN ORDER TO RETRIEVE SOME PAX. WE RECEIVED THE STANDARD CLRNC FROM LAS VEGAS ATC AND FLEW IT UNEVENTFULLY FROM THE ARPT TO THE BOULDER CITY VOR. ONCE OVER THE VOR, OUR TYPICAL RELEASE POINT FROM DEP CTL, MY CAPT TOLD ME TO GO AHEAD AND SIGN-OFF WITH ATC. ATC WENT AHEAD AND TOLD US TO SQUAWK 1200. AT THE TIME WE WERE LEVEL AT 5500 FT. AS SOON AS WE WERE RELEASED HE STARTED A NEAR MAX PERFORMANCE CLB WHICH ISN'T DONE, ESPECIALLY IN AN EMPTY ACFT, AT THIS POINT BECAUSE THERE ARE STILL LEDGES OF THE CLASS B AIRSPACE OVERHEAD. SINCE I WASN'T SURE OF THEIR ALTS, I GOT MY CHARTS OUT AND QUICKLY RESEARCHED. BY THE TIME I FOUND THE INFO WE WERE ALREADY BACK IN THE CLASS B. I SHOWED THE CAPT THE CHART, WHICH HE LOOKED AT WITH INITIAL SUSPICION, BUT THEN HE PUSHED THE NOSE OVER SO AS TO AVOID THE LAST LEDGE. NOTHING EVER CAME OF THE AIRSPACE BREACH. THIS CAPT IS ONE OF THOSE FROM THE OLD SCHOOL WHO DOESN'T PUT MUCH STOCK IN YOUNGER PLTS IN THE R SEAT. I SHOULDN'T HAVE LET THAT STOP ME FROM QUESTIONING HIM STRONGLY BEFORE I LOOKED AT THE CHART.
