moving to second place in viewers and winning some hours in the money demo.

It won't last however.

When they showed a diagram of a airplane… he said you a describing what a plane looks like? 90% of your viewers stare out the window to look at the plane they are about to get on."


Maher was doing a general critique of the news media he said. "Fox is for conservatives, MSNBC is for liberals, CNN is for airports."

Landing at Gimli

In line with their planned diversion to Winnipeg, the pilots were already descending through 35,000 feet (11,000 m)[2] when the second engine shut down. They immediately searched their emergency checklist for the section on flying the aircraft with both engines out, only to find that no such section existed.[3] Captain Pearson was an experienced glider pilot, which gave him familiarity with flying techniques almost never used by commercial pilots. To have the maximum range and therefore the largest choice of possible landing sites, he needed to fly the 767 at the "best glide speed". Making his best guess as to this speed for the 767, he flew the aircraft at 220 knots (410 km/h; 250 mph). First Officer Maurice Quintal began to calculate whether they could reach Winnipeg. He used the altitude from one of the mechanical backup instruments, while the distance traveled was supplied by the air traffic controllers in Winnipeg, measuring the distance the aircraft's echo moved on their radar screens. The aircraft lost 5,000 feet (1,500 m) in 10 nautical miles (19 km; 12 mi), giving a glide ratio of approximately 12:1.

Three minutes later, at 06:26 UTC and approximately 65 nautical miles (120 km) from Lajes Air Base, engine #1 also flamed out.[3] Without engine power, the plane lost its primary source of electrical power. The emergency ram air turbine was deployed automatically to provide essential power for critical sensors and instruments to fly the aircraft. However the aircraft lost its main hydraulic power, which operates the flaps, alternate brakes, and spoilers. The slats would still be powered, however, when the flaps #1 position was selected.

5. The Boeing 777 is capable of a 200 mile glide

according to an expert(?) on the BBC a couple days ago.

I imagine that long of a glide is achievable only if the engines fail at or near the plane's max altitude.

They must believe the Conservative half of the audience is ignorant and needs explaining. They are probably right!

......they only carry one story. Jeff Zucker moved from NBC's entertainment division to head CNN and now they're a pure ratings player. Very sad indeed.
