Narrative:

5 or 6 small aircraft aircraft operating in closed pattern for multiple touch and go's on runway 22 cmi. Aircraft also making lndgs on runway 32 cmi (these runways bisect each other). On downwind, small aircraft X (departing aircraft) was cleared touch and go on runway 22 following another small aircraft in pattern just ahead. Clearance acknowledged. Landing made. Instrument giving verbal assistance to student where necessary, called out items on checklist for takeoff while setting up aircraft for the go phase. Student began takeoff full throttle, drifting left due to insufficient control with the crosswind existing. Instrument commenting. Just prior to lift off heard female voice in tower scream, 'stop, small aircraft X, stop!!' instrument immediately closed throttle, started braking (caused a couple of flat spots on tires), looked left to see twin small transport Y airliner (turbo propeller) about to T/D on runway 32. Tower telling small transport Y commuter to 'go around,' small aircraft X added power to accelerate across runway 32 as opposed to nearly stopping on runway 32. Timing was such that if small aircraft X continued with touch and go the small transport Y could have landed on runway 32 well after small aircraft X crossed runway 32. But with small aircraft X approaching runway 32, then attempting stop, put small aircraft X in critical position (on runway 32) for landing commuter. Observer on board (student in rear seat) said he heard something about small aircraft X from tower, but too much right/T communications to realize what was being said. Between my comments on hot microphone within our aircraft, considerably communications on tower frequency, change of tower controller from male to female, occupants of small aircraft X did not hear or acknowledge or recognize any communication from tower until woman's scream for small aircraft X to stop. Corrective actions: tower should receive acknowledgement before assuming aircraft heard and will comply with their xmissions. Instrument (reporter) should reduce comments to student so that hot microphone xmissions (intercom) will not block tower xmissions.

Title: SMA CLEARED TOUCH AND GO ON RWY 22, TOOK TOO LONG ON RWY AND CAUSED SMT TO GO AROUND ON INTERSECTING RWY 32.

Narrative: 5 OR 6 SMA ACFT OPERATING IN CLOSED PATTERN FOR MULTIPLE TOUCH AND GO'S ON RWY 22 CMI. ACFT ALSO MAKING LNDGS ON RWY 32 CMI (THESE RWYS BISECT EACH OTHER). ON DOWNWIND, SMA X (DEPARTING ACFT) WAS CLRED TOUCH AND GO ON RWY 22 FOLLOWING ANOTHER SMA IN PATTERN JUST AHEAD. CLRNC ACKNOWLEDGED. LNDG MADE. INSTR GIVING VERBAL ASSISTANCE TO STUDENT WHERE NECESSARY, CALLED OUT ITEMS ON CHKLIST FOR TKOF WHILE SETTING UP ACFT FOR THE GO PHASE. STUDENT BEGAN TKOF FULL THROTTLE, DRIFTING LEFT DUE TO INSUFFICIENT CONTROL WITH THE XWIND EXISTING. INSTR COMMENTING. JUST PRIOR TO LIFT OFF HEARD FEMALE VOICE IN TWR SCREAM, 'STOP, SMA X, STOP!!' INSTR IMMEDIATELY CLOSED THROTTLE, STARTED BRAKING (CAUSED A COUPLE OF FLAT SPOTS ON TIRES), LOOKED LEFT TO SEE TWIN SMT Y AIRLINER (TURBO PROP) ABOUT TO T/D ON RWY 32. TWR TELLING SMT Y COMMUTER TO 'GO AROUND,' SMA X ADDED PWR TO ACCELERATE ACROSS RWY 32 AS OPPOSED TO NEARLY STOPPING ON RWY 32. TIMING WAS SUCH THAT IF SMA X CONTINUED WITH TOUCH AND GO THE SMT Y COULD HAVE LANDED ON RWY 32 WELL AFTER SMA X CROSSED RWY 32. BUT WITH SMA X APCHING RWY 32, THEN ATTEMPTING STOP, PUT SMA X IN CRITICAL POS (ON RWY 32) FOR LNDG COMMUTER. OBSERVER ON BOARD (STUDENT IN REAR SEAT) SAID HE HEARD SOMETHING ABOUT SMA X FROM TWR, BUT TOO MUCH R/T COMS TO REALIZE WHAT WAS BEING SAID. BTWN MY COMMENTS ON HOT MIC WITHIN OUR ACFT, CONSIDERABLY COMS ON TWR FREQ, CHANGE OF TWR CTLR FROM MALE TO FEMALE, OCCUPANTS OF SMA X DID NOT HEAR OR ACKNOWLEDGE OR RECOGNIZE ANY COM FROM TWR UNTIL WOMAN'S SCREAM FOR SMA X TO STOP. CORRECTIVE ACTIONS: TWR SHOULD RECEIVE ACKNOWLEDGEMENT BEFORE ASSUMING ACFT HEARD AND WILL COMPLY WITH THEIR XMISSIONS. INSTR (RPTR) SHOULD REDUCE COMMENTS TO STUDENT SO THAT HOT MIC XMISSIONS (INTERCOM) WILL NOT BLOCK TWR XMISSIONS.
