At first I couldn't hear it, but from the second chorus (before the bridge) onwards it's plain as day.
Reminds me of how Stevie Nicks just turns up out of nowhere to sing backup on this one:
A little more obvious, but maybe that's because someone pointed it out when they first shared it to me.
The crew actually thought he was dead, but "Fortunately they held onto him in fear that his body might get sucked into the plane’s engine."
Now the writer is perhaps a little more cheered by this inadvertent real-world experiment than is warranted. But I can't blame him for looking for a tonic to the daily news.
And it IS nice to see that the one extant example we do have turned out this way.
