The Museum of Flight will host its fifth Pop-up Donor Center blood donation event in August for Bloodworks Northwest.

The pop-up will be open Aug. 11-14 in the Skyline Room at 9404 E. Marginal Way S., Seattle.

Donors will receive 50% off future admission and 20% off gift shop purchases. Masks are required.

Because of high blood usage at local hospitals and donors staying home during the heatwave, blood supplies in the area are unusually low.
