那麼這個人說的，美國人用C4炸毀管道是不是正確的呢
嗯，讓我們先看看他在自己網站上寫的原文
“The C4 attached to the pipelines would be triggered by a sonar buoy dropped
by a plane on short notice, but the procedure involved the most advanced signa
l processing technology. Once in place, the delayed timing devices attached to
 any of the four pipelines could be accidentally triggered by the complex mix
of ocean background noises throughout the heavily trafficked Baltic Sea—from
near and distant ships, underwater drilling, seismic events, waves and even se
a creatures. To avoid this, the sonar buoy, once in place, would emit a sequen
ce of unique low frequency tonal sounds—much like those emitted by a flute or
 a piano—that would be recognized by the timing device and, after a pre-set h
ours of delay, trigger the explosives."

"On September 26, 2022, a Norwegian Navy P8 surveillance plane made a seemingl
y routine flight and dropped a sonar buoy. The signal spread underwater, initi
ally to Nord Stream 2 and then on to Nord Stream 1. A few hours later, the hig
h-powered C4 explosives were triggered and three of the four pipelines were pu
t out of commission. Within a few minutes, pools of methane gas that remained
in the shuttered pipelines could be seen spreading on the water’s surface and
 the world learned that something irreversible had taken place."
