Henry according to the info I have, you are correct, Gee came first. In a nutshell, Gee was a system of transmitters that laid out a radio grid across Europe. It allowed the aircraft navigators, using a CRT and special Gee charts on the aircraft, to establish a position when they were within 400 miles of the home transmitters. Accuracy at max range was within six miles. The first raid was carried out against the Krupp works in Essen, on March 8, 1942. 211 bombers were used, 82 of which were fitted with Gee. The raid was considered a failure, since the bombs fell just about everywhere
except on the Krupp works. The second raid using Gee was on the night of March 28, against Lubeck. It was considered a success, in that 200 acres of the city were levelled, with 2000 buildings destroyed.. .. .Bex, you weren't seeing things. That four bladed propeller mod on the Twotter is done by Zimex, I believe. They use the series 300 with the PT6-27 engines, flat rated to 620 SHP. <img border="0" title="" alt="[Smile]" src="smile.gif" />
