Narrative:
Radar vectors during departure and climb from bfi. Multiple light aircraft in area necessitating vectors on SID. We were northwest of sea and cleared 'turn right to join airway (J90).' shortest distance to join airway was direct sea. We were queried as to assigned heading after frequency change. Replied, 'right turn to join airway, proceeding direct sea.' we were given vector, 'heading 070 degrees direct dsm when able.' instead of giving arbitrary clrncs, provide specific heading for expected results. No conflict occurred.

Title: FLC OF A DC8 FAILED TO FOLLOW THE RADAR VECTOR CLRNC TO JOIN AIRWAY WHEN TURNING DIRECT TO THE VOR INSTEAD OF INTERCEPTING THE AIRWAY FURTHER OUTBOUND ON THE AIRWAY.
Narrative: RADAR VECTORS DURING DEP AND CLB FROM BFI. MULTIPLE LIGHT ACFT IN AREA NECESSITATING VECTORS ON SID. WE WERE NW OF SEA AND CLRED 'TURN R TO JOIN AIRWAY (J90).' SHORTEST DISTANCE TO JOIN AIRWAY WAS DIRECT SEA. WE WERE QUERIED AS TO ASSIGNED HDG AFTER FREQ CHANGE. REPLIED, 'R TURN TO JOIN AIRWAY, PROCEEDING DIRECT SEA.' WE WERE GIVEN VECTOR, 'HDG 070 DEGS DIRECT DSM WHEN ABLE.' INSTEAD OF GIVING ARBITRARY CLRNCS, PROVIDE SPECIFIC HDG FOR EXPECTED RESULTS. NO CONFLICT OCCURRED.
