A Riot of Glorious Knowledge: August 2010

Communications blackout - Wikipedia, the free encyclopedia: "mple, endured such a blackout for four minutes, beginning at 9 minutes 5 seconds into the flight.[2]

For Apollo missions, the communications blackout was approximately three minutes long.[3] For Apollo 16, for example, pre-advisory data (PAD) for re-entry listed the expected times for re-entry communications blackout to be from 0 minutes 16 seconds after entry interface to 3 minutes 33 seconds after entry interface (a total of 3 minutes 17 seconds).[4] For the Apollo 13 mission, the blackout was much longer than normal because the flight path of the spacecraft was unexpectedly at a much shallower angle than normal.[4] According to the mission log maintained by Gene Kranz, the Apollo 13 re-entry blackout began at 142:39 and ended at 142:45, and was 1 minute 27 seconds longer than had been predicted.[5]

Communications blackouts for re-entry are not solely confined to entry into Earth's atmosphere. They apply to entry into any atmosphere where such ionization occurs around a craft. The Mars Pathfinder endured a 30 second communications blackout as it entered Mars' atmosphere, for example. The Huygens probe endured a communications blackout as it entered the atmosphere of Titan.[1]

Until the creation of the Tracking and Data Relay Satellite System, the Space Shuttle would, like Gemini, Mercury, Apollo, and others, endure a 30 minute long communications blackout before landing. However, the Shuttle can communicate with a Tracking and Data Relay Satellite during re-entry. This is because the shape of the Shuttle creates a 'hole' in the ionized air envelope, at the tail end of the craft, through which it can communicate upwards to a satellite in orbit and thence to a ground station.[1]

Friendly-fire

A document dating September 3, 2006 suggests that four Canadian soldiers died in the Panjwaye District of Afghanistan during Operation Medusa, when an American jet dropped a bomb on a building they occupied during the second day of the operation. Seven other Canadian soldiers and one civilian were also reported to have been wounded in the attack.^[47]^[48] At the time, the Canadian military reported that the deaths and injuries were caused by a firefight with the Taliban, which it still insists. Michel Drapeau, a former colonel with the Canadian Forces, commented that the document is disturbing, due to it differing from the military's report at the time of the soldiers' deaths, which could make the document incorrect.

The patrol returned to base.

It started with a suicide bomb. On 4 March 2007 a convoy of US marines, who arrived in Afghanistan three weeks earlier, were hit by an explosives-rigged minivan outside the city of Jalalabad.

The marines made a frenzied escape, opening fire with automatic weapons as they tore down a six-mile stretch of highway, hitting almost anyone in their way – teenage girls in fields, motorists in their cars, old men as they walked along the road. Nineteen unarmed civilians were killed and 50 wounded.
