Not just aircraft, an entire organisation, though mainly to rescue those that ditched rather than lead them home - though that undoubtedly happened when a damaged aircraft was located and an escort reached it. ( P-47, not Mosquito.)

….”The duty day at Saffron Walden started much the same as at the bomber and fighter groups, with the arrival of the 8th AF Field Order, by teletype, in the early hours. The duty controller then plotted the “IN” and “OUT” courses to be flown by the bombers and fighters, and based on this, he chose the rendezvous points in the Channel and the North Sea, where he would place his boats.
The same would be done for Detachment B’s P-47s, and all units were then notified of courses and RV points, and times to be on station. The boats required 3 hours minimum notice, with 1 hour for the P-47s and the other spotter aircraft.
The P-47s always operated in pairs, one to stay low and orbit the customer in the water, the other to stay high and handle communications and to provide a “target” for the fixing stations, and to provide armed cover. When their fuel state required it, they would be relieved by another pair.
The duty controller also brought all of his fixer stations, ground and air based radio relay units into operation, and the ASR service was ready for the day’s work.
From the beginning of 1944, all Allied aircrew’s direct link with ASR assistance was through channel “B” on their VHF radio. Using the universal distress code MAY-DAY, they were in immediate contact with the ASR controller, who would often ask for a long transmission if the pilot’s circumstances allowed it.
This improved the chances of the fixer stations getting a bearing. A pilot wounded or with damaged equipment could often only provide a brief and fragmentary transmission, which made it very difficult to obtain a fix.
This data was passed on to the appropriate rescue squadron and the closest launches. (The boats routinely monitored “B” channel themselves.) With the passage of time and experience the system worked well for the aircrew with the proper training to do their part, and a healthy dose of good luck.
The contributions of anonymous ASR controllers and the operators of the fixer stations brought hundreds of airmen home from the deep.”….
