What happens when you record on video the plane's blades with a Nokia N95 mobile phone.

Wait...they still have passenger planes with external blades? Holy crap...I've fallen backwards through TIME!

Haven't you ever heard of turboprops?

You can still buy Fokker Friendships new.

Sure. For low flight speeds turboprops are way more fuel-efficient than regular turbine engines. Which is why they are used quite a lot in European flights. I sit in a turboprop plane about once every two months.

We have turboprops that leave our city on the eastern coast of Lake Michigan and fly you over the lake (80miles) to Milwaukee or Chicago. Or maybe take you to Detroit on the other side of the state, so you can catch a flight on a passenger liner.

There will be more external bladed engines in your future. Think of a turbofan engine as just a turboprop engine with a smaller, densely bladed prop encased in a shroud. A turbo prop engine is just a turbo fan engine with a very large, sparsely bladed fan without a shroud.

A lot of work is currently going into a new intermediate concept called propfan, which is half way between a turbofan and a turboprop. It's an externally bladed engine with lot more shorter blades then traditional turboprop, but without the shroud, and with longer blades, then of the conventional turbofan.

Reminds me of a joke, Zen.

A World War II pilot is reminiscing before school children about his days in the air force. (Joke best delivered with a good thick accent)

"In 1942," he says, "the situation was really tough. The Germans had a very strong air force. I remember, " he continues, "one day I was protecting the bombers and suddenly, out of the clouds, these fokkers appeared.

(At this point, several of the children giggle.)

I looked up, and right above me was one of them. I aimed at him and shot him down. They were swarming. I immediately realized that there was another fokker behind me."

At this instant the girls in the auditorium start to giggle and boys start to laugh. The teacher stands up and says, "I think I should point out that 'Fokker' was the name of the German-Dutch aircraft company"

"That's true," says the pilot, "but these fokkers were flying Messerschmidts."

No Folke Wulf - 190 jokes?

Could be dangerous to folke a wulf.

I always liked the DR1, It was a pleasant little fokker.
