    The bomb was a 4000lb Cookie (sometimes referred to as a Blockbuster) which was first used on the raid to Emden on the night of 31 March 1941.The Cookie was delivered by a specially modified Wellington Mk1C of No 149 Squadron.

    Its destructive power in built up area targets was recognised and it was on the mixed menu loading for bomb loads from then on unless a complete incendiary load was preferred.

    For the raid on Essen on the night of 10 April 1942, a 8000 lb Cookie (Blockbuster) was dropped by a Halifax of No 76 Squadron.The bomb was really two 4000lb Cookies with the two bomb casings welded together.

    Further development of high capcaity (HC) Cookie /Blockbuster bombs became a priority to deal with the U Boat pens after it was revealed that the 2000lb bomb was incapable of penitrating the outer concrete skin.

    Did the 4000lb Blockbuster have any anti-handling features or use delays or did this one simply not detonate because it landed in water ?

    It doesn't look like a bomb, rather more like an old hot-water cylinder. It's a good job that the local scrap metal "Mautschrankers" didn't find it first or it would have been straight in the smelter !:unsure:

    Rich, IIRC the cookies' three pistols were so sensitive that even if jettisoned without being armed they'd often go off on hitting the ground:lol: God knows what the explosion rate was for damaged aircraft crashlanding with them still aboard - or how many damaged aircraft were destroyed by their OWN ordnance when it was dropped...a cookie would loft debris and shrapnel 5,000 feet into the air!

    All - Mosquitos, especially the later bomber types with bulged bombdoors - could and did carry the 4,000lb HC cookie too.

    Latest reports are that the bomb has been successfully defused.

    Craig,

    I have just read that on the BBC website.

    If it had gone off it would have effected an area the radius of 1.5.kilometers.

    It has caused the biggest evacuation in Post war Germany up to now.

    Glad all went well.

    Regards
    Tom

    I saw in the German press that they were hoping to defuse the bomb on Sunday.In the past the RAF disposal teams have been consulted for technical assistance where
    this was found neccessary.

    Over 40 years ago,the Germans called in RAF bomb disposal personel for assistance when they found a unexploded Upkeep bomb.

    As regards "hang ups" of Cookies,the crew would have some idea that the bomb had not been released and there was always the option to abandon the aircraft in a safe area.

    There was a case of things going wrong whilst bombing up on No 61 Squadron Lancaster at Syerston in early December 1942.The aircraft for some reason caught fire and fired the incendaries.The groundcrew engaged in the bombing up and preparation of the aircraft for that night's operation to Turin,fled the scene for safety,some on bikes.It was said that some runners exceeded the pace of those on bikes.

    The Station commander,Groupt Captain Gus Walker, saw the fire from the control tower and attended the scene with the RAF Firecrew.Walker, seeing the firing incendaries,proceeded to rake them away from underneath the aircraft in a vain attempt to safeguard the 4000lb Cookie from exploding.The Cookie exploded killing one of the Firecrew and hurling Walker some distance,severely injuring him but he lived to tell the tale at the expense of losing his right arm.He was back in charge of Syerston within two months and went on to serve as OC No 1 Group postwar.

    There was other cases of Cookie detonating when bombed up for the night's operations.A case in 1945 at East Kirkby (No 61 or No 630 Squadron comes to mind which severely damaged a T2 hanger and destroyed several parked Lancasters.

    A dangerous occupation being a armourer,whether it be as a squadron armourer or as a station armourer, carrying out duties at the bomb dump.

    About 50,000 people in Hannover have been evacuated from their homes while experts defuse three British bombs dating from World War Two.
    two unexploded bombs had been defused, and a third - which was severely damaged - might have to be made safe using a specialised cutting machine.

    Two other suspected bombs had turned out to be harmless scrap metal, it said.

    It's a Cookie without doubt....blast bomb/blockbuster.....main loading of the many variations of bomb loads,rest of the load made up of incendiaries....intended for urban areas.

    The Cookie,the result of improving the blast effect by the utilisation of a better explosive filling of RDX/TNT and a thin casing which increased the charge to weight ratio (CWR) to 85% although the Frankfurt bomb has been declared to have a CWR of about 75%.

    Later versions of the Cookie used a Amatex fill which was also used in the 8000lb and 12000lb bombs bombs.....no more than 4000lb Cookies with their casings bolted together in two or three sections as the case might be.The three section HC bomb had the inflexibility that only modified Lancasters could carry it.

    Unlike most threads, this one will continue to be topical and dynamic for decades to come:

    "While the Western media has concentrated its creative attention on the London Blitz, it is seldom pointed out that more bombs were dropped on Berlin alone than were dropped on all of Britain during the entire war! Sixty years after the war, Germany is still destroying the thousands of tons of unexploded bombs, shells, mines and grenades out of the millions of tons of often toxic explosives the Allies deposited on them. Weapons experts estimate that it could take up to 150 years before such clearance work ends. It is estimated that 5 percent of the 440,000 Allied bombs dropped on Berlin failed to explode due to faulty fuses, poor assembly, bad angle of impact and other reasons."

    "A great danger are bombs which had delayed-action fuses. 10 to 20 percent failed to detonate and are still in the ground. "
