How long is the longest you've managed to keep a shuttlecock going in badminton?

When I played with someone today we managed to keep it in the air and kept going for about a minute. What is the longest you've managed to keep one going for?|||about 2 mminutes, the net wsnt regulation|||Longest is probably a minute and a half in a doubles match. Lots of smashing but couldn't kill. Great defence and no mistakes until another guy's net shot hit the net. Rallies don't count when all you're doing is clearing and novice matches especially backyard badminton where the only shot is a simple tap or a "half court clear" (not really even a clear)
