Over a thousand slaves forced to work on the production of these weapons were herded into a barn which was then set on fire in the Gardelegen massacre. After the damage from these weapons was blamed on exploding gas mains, people started humorously referring to them as "flying gas pipes." A never-used version of these weapons was housed in the fortress of Mimoyecques and was irreparably damaged in Operation Crossbow, which targeted these weapons for destruction via aerial bombing. Operation (*) Paperclip granted political amnesty to many scientists in exchange for their expertise gained while developing these weapons. The first version of these weapons was a winged bomb nicknamed "buzz bombs," while the widely-feared second version was the brainchild of Wernher von Braun and was a liquid-fuelled ballistic missile that could strike a target more than 200 miles away flying at over Mach 3. For 10 points, name these long-distance German "vengeance weapons."
