4. The Strange Great Panjandrum
The Great Panjandrum was supposed to be developed in secrecy in order to spring it as a surprise on the Germans. However, testing was conducted on a popular beach, so huge crowds gathered to gawk at the strange device. The design’s flaws emerged at the first trial run in 1943. When the rockets were ignited and the device was launched, it made its way up the beach before rockets on one of the wheels malfunctioned, causing the Great Panjandrum to careen wildly off course. The problem persisted in additional trials: it was impossible to get the rockets on both sides to ignite simultaneously or to keep firing simultaneously.
After weeks of troubleshooting, the developers returned to the beach, this time with a third wheel affixed to the device to increase its stability. That test proved more embarrassing yet, as the device hurtled toward the beach, only to double back and turn back to sea towards the launching craft. In the meantime, some of the rockets had detached from the Great Panjandrum’s wheels to launch themselves at the observers on the beach, whistling over their heads or exploding underwater nearby.
