On 13 March 1945, HQ 8th AF ordered the OSS J-E Project transferred to the 492nd Bomb Group's Liberator base at RAF Harrington, Northamptonshire. The 492nd continued using Redstocking to identify the Mosquito missions. On 14 March two Mosquitoes and an A-26 flew to Harrington followed on the 15th by other Mosquitoes and A-26s. The 25th BG aircrew flew the OSS Mosquito JE missions until 492nd men completed training on this aircraft type. Both Mosquito and A-26 remained stationed at Harrington, and on occasion a Mosquito flew to Watton for inspection. OSS J-E project personnel at RAF Harrington questioned the competency of 492nd BG maintaining the Mosquito and J-E operations, and frequently consulted RAF Watton. Aborts excluded, the 654th Bombardment Squadron flew 30 Joan-Eleanor Mosquito missions from RAF Watton on behalf of the OSS over the Netherlands and Germany, and an additional 21 J-E Mosquito missions from RAF Harrington. 492nd flew 10 J-E Mosquito missions.
