Firedump: 3C-QRF

In past posts on TYR, we’ve often mentioned a BAC-111 aircraft registered 3C-QRF, serial number 61. This plane belongs to the curious Jetline International of Sharjah, who we’ve discussed quite a bit. Aerotransport.org lists 3C-QRF as operated by Jetline for San Air General Trading, Richard Chichakli’s firm, which is now on the UN sanctions blacklist…

A simple theory of cancel culture - by Joseph Heath
As the institution of the charivari makes clear, people in medieval European societies took a keen interest in one another’s domestic affairs. Private life, as most of us understand it, is an 18th century innovation. The important point is not that society is reverting to an older set of norms, but that the scale of […]

AI Mark VIII radar - Wikipedia
Although the precise origins of the concept are unknown, on 8 March 1941 Bernard Lovell recorded the concept of lock-follow in his notes for the first time...The system worked by having two dipole antennas instead of one, slightly offset on either side of the mounting mast projecting through the middle of the parabolic dish. Being […]
Radar, Anti-Aircraft No. 3 Mk. 7 - Wikipedia
In 1941, an engineer at BTH, L.C. Ludbrook, began development of a lock-follow system for the SLC. This used simple electronics that were fed the paired signals and output a current whose magnitude depended on the amount of difference between the two. This signal was then sent into amplidynes that amplified the signal and drove […]
