Indeed, not so fast blaming ATC solely... (approx. timestamps on the Liveatc track)
08:58 BFI GND: ... you want to do a VFR pattern and then depart IFR
09:05 VJ Dutch pilot: Affirm
09:10 GND tx. difficult to read due to strong background n/voices in the TWR; pilot requests 'say that again'
09:16 BFI GND:... once you do the lap and the land, you'll be departing south IFR, correct?
09:26 VJ Dutch pilot: Affirm
Both sides truggled to get a clear picture of the other side's intentions while still on the ground. Non std. phraseology "the lap and the land" should better have been avoided, and certainly not 'Affirmed' if not completely understood.
Once airborne, the level of confusion on both sides, grew rapidly...
