Flight Crew Returned To Departure Airport
Aircraft; Human Factors; Procedure
The pilot's pitot cover (upper) was placed in position without a streamer attached. It was not discovered still in place by both pilots during preflight walk around. I was Pilot Monitoring in the right seat. In the takeoff roll at approximately 80 knots I called out no airspeed on the left side. Pilot Ffying after processing my call out continued the takeoff rather than executing a high speed abort. Once airborne; we notified ATC that we had an instrumentation issue and we had to return to the airport. The landing was normal.Three main take-aways I got from this are never put a cover on that doesn't have a streamer attached. Be more aware and less complacent during the preflight walk around and finally; at 80 knots instead of calling out the problem; I should have simply called for an abort.

Corporate flight crew reported they departed with a Pitot Tube cover still attached.
