Narrative:

Myself and a high time student (1300 hours) were flying a PA34-200 seneca. When we entered the pattern there was a TA stating runway 29 was in use. After we landed, the runway in use was switched to runway 2. We were clear of all runways performing our after landing checklist, holding at a complete stop. I noticed an aircraft that turned onto the approach end of runway 29 and the strobe lights came on indicating the beginning of a takeoff roll. Neither I nor my student heard any radio calls from the departing mooney. A moment or two later, I heard a cessna 152 call up on the CTAF saying he was departing runway 2, remaining in the pattern. At this particular airport, there is a large area of trees between the first half of both runways severely limiting visibility between the two runways. The 2 aircraft were rolling at the same time, and rotated at approximately the same time. The 2 aircraft missed each other by approximately 50 ft vertically and almost no lateral separation. The mooney being the faster of the two, was climbing quicker and went over the top of the C152. The mooney appeared to have seen the cessna as it went over the top and banked hard as it passed over the top. The mooney then exited the pattern. The cessna did not appear to have seen the mooney at all.

Title: PLT OBSERVES NMAC BTWN 2 ACFTS DEPARTING FROM INTERSECTING RWYS AT EVB.

Narrative: MYSELF AND A HIGH TIME STUDENT (1300 HRS) WERE FLYING A PA34-200 SENECA. WHEN WE ENTERED THE PATTERN THERE WAS A TA STATING RWY 29 WAS IN USE. AFTER WE LANDED, THE RWY IN USE WAS SWITCHED TO RWY 2. WE WERE CLR OF ALL RWYS PERFORMING OUR AFTER LNDG CHKLIST, HOLDING AT A COMPLETE STOP. I NOTICED AN ACFT THAT TURNED ONTO THE APCH END OF RWY 29 AND THE STROBE LIGHTS CAME ON INDICATING THE BEGINNING OF A TKOF ROLL. NEITHER I NOR MY STUDENT HEARD ANY RADIO CALLS FROM THE DEPARTING MOONEY. A MOMENT OR TWO LATER, I HEARD A CESSNA 152 CALL UP ON THE CTAF SAYING HE WAS DEPARTING RWY 2, REMAINING IN THE PATTERN. AT THIS PARTICULAR ARPT, THERE IS A LARGE AREA OF TREES BTWN THE FIRST HALF OF BOTH RWYS SEVERELY LIMITING VISIBILITY BTWN THE TWO RWYS. THE 2 ACFT WERE ROLLING AT THE SAME TIME, AND ROTATED AT APPROX THE SAME TIME. THE 2 ACFT MISSED EACH OTHER BY APPROX 50 FT VERTLY AND ALMOST NO LATERAL SEPARATION. THE MOONEY BEING THE FASTER OF THE TWO, WAS CLBING QUICKER AND WENT OVER THE TOP OF THE C152. THE MOONEY APPEARED TO HAVE SEEN THE CESSNA AS IT WENT OVER THE TOP AND BANKED HARD AS IT PASSED OVER THE TOP. THE MOONEY THEN EXITED THE PATTERN. THE CESSNA DID NOT APPEAR TO HAVE SEEN THE MOONEY AT ALL.
