Narrative:

Departing from charlotte amalie harbor; st thomas; as PNF/captain in aircraft #1; takeoff and initial climb out were uneventful. At approximately 600 ft aircraft #2 overtook us from above and behind after departing seconds after my aircraft. Aircraft #2 filled our windscreen as the pilot announced 'boo -- you can't out-fly a jump pilot!' on company frequency. I estimate that aircraft #2 was merely 50 ft away and lingered there for a few seconds. Aircraft #2 then climbed away to a point that it was no longer a hazard and both flts continued to the same destination. Both aircraft were carrying passenger on a scheduled revenue flight. During the event the PF/first officer of my aircraft maintained a normal climb profile as we continued to perform normal cockpit duties. He did not abruptly turn away; although aircraft #2 was dangerously close. I believe this was the best course of action at the time because it would have been imprudent and unsafe to veer away abruptly toward terrain at such a low altitude.

Title: DHC-6 TWIN OTTER FLT CREW HAS ENCOUNTER WITH ANOTHER ACFT DEPARTING TIST.

Narrative: DEPARTING FROM CHARLOTTE AMALIE HARBOR; ST THOMAS; AS PNF/CAPT IN ACFT #1; TKOF AND INITIAL CLBOUT WERE UNEVENTFUL. AT APPROX 600 FT ACFT #2 OVERTOOK US FROM ABOVE AND BEHIND AFTER DEPARTING SECONDS AFTER MY ACFT. ACFT #2 FILLED OUR WINDSCREEN AS THE PLT ANNOUNCED 'BOO -- YOU CAN'T OUT-FLY A JUMP PLT!' ON COMPANY FREQ. I ESTIMATE THAT ACFT #2 WAS MERELY 50 FT AWAY AND LINGERED THERE FOR A FEW SECONDS. ACFT #2 THEN CLBED AWAY TO A POINT THAT IT WAS NO LONGER A HAZARD AND BOTH FLTS CONTINUED TO THE SAME DEST. BOTH ACFT WERE CARRYING PAX ON A SCHEDULED REVENUE FLT. DURING THE EVENT THE PF/FO OF MY ACFT MAINTAINED A NORMAL CLB PROFILE AS WE CONTINUED TO PERFORM NORMAL COCKPIT DUTIES. HE DID NOT ABRUPTLY TURN AWAY; ALTHOUGH ACFT #2 WAS DANGEROUSLY CLOSE. I BELIEVE THIS WAS THE BEST COURSE OF ACTION AT THE TIME BECAUSE IT WOULD HAVE BEEN IMPRUDENT AND UNSAFE TO VEER AWAY ABRUPTLY TOWARD TERRAIN AT SUCH A LOW ALT.
