Very cool video. I wonder what the fighter jets could actually achieve by pulling up alongside like that? I don't suppose they could do any kind of visual inspection or signaling at that distance - even though one did seem to inch closer at one point.
The wording from the airline statement was a bit funny: "the German Air Force deployed its aircraft to ensure the safety of the flight and its guests" - considering that their main purpose was presumably to blow up the jet if it posed a threat.
On a side note, I had never seen a video like this before and it really drives home what massive amounts of exhaust these machines put out.

Not every case of lost communication with an aircraft is due to hijacking. Sometimes it's due to a serious accident on board, such as cabin depressurisation. [0]
In these cases, observations from the intercepting aircraft can be vital to understanding the circumstances leading up to a plane crash.
As far as I know they fly close enough to look into the cockpit if they don't get a response. Also, if it is just a pilot error fighter jets appearing should quickly get their attention, have them check radios etc, and/or follow the jets to the nearest airport.
(After 9/11 a law was added in Germany that would permit shooting down a plane if there is no other option to prevent it being used in a sucessful attack, but said law was scrapped by the constitutional court. There has been some public debate about what to do in case such a situation happens anyways)
Actually there us much they can do. First off they can verify that people are awake. Some depressurization or fire events can see everyone knocked out. They can also verify the exact location and identity of the aircraft. If bad actors are in control the transponders and other locators cannot be trusted.
If the pilot isnt responding to the radio, say if he turned to the wrong freq, then reports from passengers/crew of fighter jets will see the pilots recheck all coms gear. Them being there tells the pilots that something is very wrong, that they should start talking asap.
The fighters are trying to get the attention of passengers. Thats much safer than getting in front where the crew can see them (crew rarely look out the windows without good reason anyway).
Candian cf18s have a light mounted below the pilot to illuminate intercepted aircraft at night. Blink that a couple time and passengers will start screaming about UFOs.

It just looks this massove, but that's mistly due to condensation of water vapor.
Sure, those engines have a massive throughput of air, but the visible "exhaust" is barely the result of burning kerosene.
And water vapor from the burnt fuel. Hydrocarbon + o2 = co2+h2o. Those contrails are burnt fuel, just like car exaust on a cold day. The water is a product of burning.
These rules are an international recommendation (set in the "Rules of the Air" by ICAO), so while the link technically is US-only the procedure described in it is not.
Yes. They are taught pre-solo. I've been flying almost 20 years, so I can't swear exactly whether they were on the FAA knowledge ("written") test or not, but these are taught very early on as part of ground school.
Many kneeboards and emergency procedure checklists have them handy as well.
Realistically, if you can remember to tune to 121.5 MHz (the universal VHF emergency frequency), that's going to be good enough for all but lost comms. For a lost comms scenario (including electrical failure), the intercept procedures are unlikely to come into play; you'll instead proceed to an airport and land.
