The heat transfer from thin wires to He II has been investigated at low hydrostatic pressures on ground and at milligravity on board of the NASA KC-135 aircraft. The peak heat flux density at low gravity is found to be less than 10% lower than the lowest laboratory values, the recovery heat flux density, however, about 50%. For the recovery heat flux density a large scatter was observed, indicating a significant drop of this quantity in the milligravity region.
