text: The photographic crew reported, "Second run into sun and one or two bombs fell. Individual runs then made. No direct hits seen. Majority of bombs fell to the east....". The second Grand Slam was brought home after several bomb runs because of the haze and the Lancaster, PB996, landed at the emergency bomber landing ground at RAF Manston. Ten Tallboys were also dropped with no effect and no aircraft were lost. On the return journey the port inner propeller of NG384 over-speeded and could not be feathered and then oil leaking out from behind the propeller caught fire and the pilot, Flight-Lieutenant F. A. Jones ordered the crew to abandon the aircraft  south of the target. Four of the crew parachuted but then the fire went out and Jones force-landed at Gosselies near Charleroi.
  Arnsberg, 19 March
  On 19 March, 19 Lancasters of 617 Squadron, six with Grand Slams and 13 with Tallboys, attacked the viaduct again as 9 Squadron attacked the Vlotho rail bridge, in fairly cloudy weather at high altitude, with thin patches lower down. The bombers were escorted by 88 Mustang IIIs from 11 Group. PD329 Y, a Lancaster without bombs from 463 Squadron carried two cameramen from the RAF Film Unit accompanied 617 Squadron. A report from 129 Squadron, part of the escorting Mustang force, called the bomber formation tight but then the bombers flew into cloud at . The squadron flew over the Möhne Dam with its barrage balloons, smoke screen and anti-aircraft fire. The cameramen in PD329 Y had been briefed to film PB966 C, flown by Flight-Lieutenant P. H. Martin and formated on its starboard side, with a cameraman in the nose turret to film the Grand Slam as it fell away and the other on the floor of the fuselage filming vertically. Closer to the target, PD329 Y dropped back and flew on the port quarter of PB966 C.
