British Tornado GR.4 from 14 Squadron together with Romanian MiG-21MF LanceR-C from 861 Fighter Squadron near Lossiemouth RAF airbase during Dacian-2005 common exercise.
The intercom cord running from the aircraft to the technician is what is referred to as the “tether.” A mechanic stands nearby, waiting for a signal from the technician to remove the chocks from under the wheels. Please also note that this MiG-25RB has an external fuel tank.
When the engines are started, the aircraft technician “hangs on the tether,” that is, listens to the pilot's report on the start-up parameters via the intercom (SPU), which is hard to make out due to static and noise.
The Indian Air Force received six MiG-25RBs. All of them bore a stylized image of an eagle—the emblem of the 102nd Squadron. One of the Indian MiG-25s was lost in a crash, but the rest remained in service until 2006.
This MiG-25RBSzs (Red 38) was photographed at Welzow, East Germany, in August 1991, while on the strength of the 11th ORAP (Otdelnyi Razvedyvatelnyi Aviatsionnaya Polk, or Independent Reconnaissance Aviation Regiment).
