“I was thinking “drug flight” too.”
Chaff must be tuned to the expected frequencies. I doubt it would effect military radars which can rapidly change frequencies to adapt to new conditions. This was some yahoo with a bit of old ordinance.
True. When the RAF used chaff when bombing Hamburg in 1942, the initial results were fantastic, wiped out German radar coverage.
But the Nazis quickly found out how it worked and changed frequencies. Of course, you could use “broadband” chaff, with filaments of different lengths, but that would increase weight and decrease hiding density...
