The patch on the back of Lambert's A-2 jacket is the Flying Tigers blood chit. These patches were issued to US pilots flying in China during WWII so they could be returned safely by Chinese people (most of whom didn't speak English) back to US air bases in China, thus saving many lives. The flag on the chit is the Nationalist Chinese flag (now Taiwan). The chit reads: "This man is an American fighting for China. Please save and protect him as a fellow soldier". Known as the Flying Tigers, these men were a group of maverick pilots flying for Chiang-Kai-Shek. In a period of 7 months, they shot down over 1000 Japanese planes in the air and ground suffering only a few casualties. The reason Lambert wears it is probably to signify that he's a maverick cop who goes back in time to capture fugitives and bring them back to the future. The jacket is government issue and doesn't include side-entry pockets.
The last series to premiere under the Lorimar Productions name.
