A Martin PBM Mariner flying boat blasts off the water using Jet-Assisted Take-Off (JATO) rockets, a technique used to shorten takeoff distance for heavily loaded patrol aircraft. Seaplanes like the PBM Mariner flew maritime patrol, search-and-rescue, and anti-submarine missions during the Korean War, and this reference image was likely gathered to illustrate the type of aircraft flown in connection with Lt. Bancroft's Navy service. Project: 218289
