I am not too familiar with Lenox blades, I usually use Diablo blades. I was surfing Youtube when I came across this almost 60 minute video of them cutting a 727 in half with one blade. The video itself it pretty boring and cutting a 727 is not really an amazing feat considering aircraft aluminum is very thin. At the end do not show you the cut, did the blade cut through the stringers too? Was there pipes and control cables involved? That would make it a bit more impressive. I know one thing next time I am on a flight and some guy whips out a reciprocating saw and a Lenox blade, I might get a bit nervous.
