retd from a spotting session at PNQ/VAPO this morning where I saw a number of fighters of various makes do their rapid takeoffs and landings.
Starnge thing i noticed: the engines had flames when seen from the rear (afterburners??) but they werent consistent , but rather kept varying in intensity as the aircraft (a Jaguar) picked up speed on the takeoff roll. Was this just an illusion or does it happen this way? And if yes why is this so? Shouldnt the thrust be consistent?
