615 VGS still (I think) holds the world record for training launches (on the longest day of the year) - 615 launches using three MkIII and two T21b... Clive Watson organised the dawn to dusk event, a rota enabled staffing with rest periods etc. We built up to “the longest day” with a couple of practice days.i don’t recall any breakages... My contribution on “the longest day” to the total? 42 launches...
