Narrative:
I was teaching a student pilot takeoff and lndgs in an small aircraft. We had done approximately 4 and were continuing a right hand traffic pattern as per tower request. (This is normal pattern at cos). I saw an medium large transport start takeoff roll, accelerate, and rotate for takeoff. Approximately 200 ft AGL the medium large transport changed pitch (flutter) and continued on. Medium large transport then asked tower if they saw that! Tower did not think there was a problem. I saw the medium large transport throughout sequence and did not see a problem. I did not alter course. I do not believe there is a possibility of a mid air in this case. Additional comments from chief pilot: I concur with pilot's conclusions. The safest place to be when flying off a cross runway and high performance traffic is using the primary runway is directly overhead at a high angle off. This is the normal practice here (and at lax, I might add) and I urge no change in the procedure. Anything else would be less safe.

Title: INSTR WITH SPI ON DOWNWIND WHICH OVER FLIES OTHER RWY HEAR MLG COMMENT TO TWR AS HE ROTATES REGARDING PROX OF ACFT.
Narrative: I WAS TEACHING A STUDENT PLT TKOF AND LNDGS IN AN SMA. WE HAD DONE APPROX 4 AND WERE CONTINUING A R HAND TFC PATTERN AS PER TWR REQUEST. (THIS IS NORMAL PATTERN AT COS). I SAW AN MLG START TKOF ROLL, ACCELERATE, AND ROTATE FOR TKOF. APPROX 200 FT AGL THE MLG CHANGED PITCH (FLUTTER) AND CONTINUED ON. MLG THEN ASKED TWR IF THEY SAW THAT! TWR DID NOT THINK THERE WAS A PROBLEM. I SAW THE MLG THROUGHOUT SEQUENCE AND DID NOT SEE A PROBLEM. I DID NOT ALTER COURSE. I DO NOT BELIEVE THERE IS A POSSIBILITY OF A MID AIR IN THIS CASE. ADDITIONAL COMMENTS FROM CHIEF PLT: I CONCUR WITH PLT'S CONCLUSIONS. THE SAFEST PLACE TO BE WHEN FLYING OFF A CROSS RWY AND HIGH PERFORMANCE TFC IS USING THE PRIMARY RWY IS DIRECTLY OVERHEAD AT A HIGH ANGLE OFF. THIS IS THE NORMAL PRACTICE HERE (AND AT LAX, I MIGHT ADD) AND I URGE NO CHANGE IN THE PROC. ANYTHING ELSE WOULD BE LESS SAFE.
