LOUD . . . . !!!
We felt the shock wave from the explosion at the Hemel Hempstead oil terminal years ago (whole house shook) and we're 30 odd miles from there in Surrey. |

Regarding the Tallboy description, is as follows per "British Explosive Ordnance NAVORD 1665 10th June 1946", page 49 Detonators—Sensitive type, delays up to 60 min. as required operationally. Exploders - Primary: 2 ring and 2 solid C.E. pellets; 4 solid RDX/Beeswax pellets - Secondary: 2 ring and 2 solid large RDX/ Beeswax pellets (placed in a special exploder tube into which the standard exploder container fits). https://bulletpicker.com/bomb_-12000...-1-tallbo.html https://cimg7.ibsrv.net/gimg/pprune....e068f126c2.png |
Thanks for that Beamr.
Are there any recorded instances of the Germans trying to defuse one? |

Interestingly, apparently in total three Tallboys were found unexploded at Sorpe dam in ´58/´59. The first one found in 1958 was defused 6th of Jan 1959, and this is mentioned in many sources throughout the internet.
BUT: the Reuters news video linked above has the headline "More Tallboys Discovered In Germany" with comment "Two more RAF 5 1/2-ton 'tallboy' bombs were found, Jan 19, in the drained Sorpe dam reservoir, North Rhine-Westphalia." So its four tallboys with the polish one counted for, I reckon there must have been more. Or be more yet to be found. |

All of the bombs were supposed to be fitted with delay fuses - twelve with a 11 second delay and the other six on a 30 minute one. However it later emerged that at least two bombs were fitted with direct impact pistols. Again there was a mosquito camera aircraft present filming the attack. |
Perhaps a little something lost in the translation?

https://goo.gl/maps/Af61GwnvF58ByLU8A And here is a post-bombing recce photo, taken 25 April 1945 (attack occurred 16 April) showing the damage to the canal vicinity, and the Lützow settled in the shallow water. The visible craters all match up nicely with the strikes seen in the video linked earlier in this thread. It is clear from this photo just how devastating that bomb between the dock edge and the battleship hull must have been! https://commons.wikimedia.org/wiki/F...April_1945.jpg

I love the details of the fuze and bomb body, I would love to see one in action live just not too close

"TNT and RDX are very stable explosives."
A wise man who wishes to live long will treat that as a relative statement it's best to treat all explosives as if they are loaded guns - they're really designed to go off |

Big brother of Tallboy here at Bielefeld Viaduct

Speaking of fuses, I read about a device - limpet mine I think - that used a boiled lolly as a delay.
Water got in, dissolved lolly, and BANG. Talk about effective low tech! |

I recently drove to the Bomber Command Museum in Nanton, south of Calgary, to see the reproduction Grand Slam and Tallboy that the museum had recently acquired. Very impressive to see in "in the flesh".

I didn't take a picture of it, because I thought I had one! https://www.bombercommandmuseum.ca PS Pugilistic Animus, do pedants have short fuses? ;) |
The reason they said was that allied bombs when being developed were typically dropped onto harder ground than that which covers most of Germany, and many bombs just literally sank into the loam. https://cimg6.ibsrv.net/gimg/pprune....ee60426f90.jpg |

I think that I have a pretty long fuse because I am a firework :} |
