Amazing 727 Video for everyone

The FO's side window was probably changed and wasn't painted.

During the roll, you can see the CA's window also with the same feature. I think it's a contrasting color so the rescue crews can find the escape window (the 2nd window on the sides open IIRC) in case of emergency.

You are correct. The sliding windows are removable for we ARFF crews to get at, but are different on different aircraft. They're outlined in the same way that some entry/cargo doors and some window areas are marked with a red outline or red corners and the words "Emergency - Cut Here", or similar; so we know where to put the K-12 saw to use.
 
I could google it but I doubt I would get the real answer I could get from MikeD.

What is a K-12 saw?

EDIT: I did google it. Other than the READY START switch, it's not much different than a concrete saw.

Never mind unless you have something of value to add.

Standard extrication saw for fire crews. Comes with different blades for cutting different surfaces.

That said, cutting into an aircraft is still a dicey operation, especially post-accident. You have to have handlines deployed, charged and ready to be brought to bear against any fire that may occur while cutting.

Case in point: In 1976, a DC-6 operated by Mercer Airlines crashed just short of VNY following losing (inflight separation) of an engine on takeoff from BUR. A landing was attempted that resulted in a touch and go since the crew couldn't stop, and while enroute to VNY, they lost another engine and couldn't stay airborne, ending up crash-landing on a golf course.

There was no post-crash fire, but fuel had pooled underneath the fuselage and left wing. The decision was made to cut into the aircraft in order to extricate the trapped and deceased cockpit crewmembers. An AFFF foam blanket was sprayed around the nose of the aircraft prior to cutting, but firefighters walking through the foam were disturbing the vapor-blanket the foam was creating. During cutting with the K-12, the fireman cut at an angle and accidently hit the production splice that mates the cockpit to the fuselage causing immediate sparks. The sparks connected with the fuel vapors causing an immediate flash fire that burned a number of firefighters. Luckily, charged handlines in place immediately extinguished that fire.
