Landing an passenger Jet in the arctic

That video brings back memories. I’ve seen comments that refer to the engines on those as hairdryers.

A A340-300 full of Filipinos each with two balikbayan boxes weighing 70 pounds a piece and that included the children. You knew that plane was heavy.

This was long ago. They lowered the weight limits to 50 pounds a number of years back.

Another really long takeoff roll. This is a 747-400 out of Chicago O'Hare, non stop to Tokyo. Takeoff roll starts at 0:35 and rotate is a full minute later at 1:35.

I need to try to fly on one before they’re gone!

I've been on a DC-10. (Chicago to Las Vegas). But never on a 747.

Cool!

Ive been on a DC-10 once, that I know of - Northwest Airlines from Memphis - Minneapolis back in June 2002.

It was a 1973 model. How do I know? Because the data plate with the year it was built was placarded above the door. Saw it as I exited the jet.

Then I flew a DC-9 from Minneapolis to Madison, WI.

So it was an all-McDonnell-Douglas trip! Such cool airplanes.

You might be too late already. I can tell you though that the experience of feeling the thrust from the four engines on takeoff never got old for me. There was always something about flying on a 747 that made it special whether it was watching kids gawk through the terminal windows or watching the other 400 plus passengers.

I know it’s off topic, but our mini-discussion on the 747 deserves these photos of the time I got to sit in the flight deck of a 747-400 freighter at the MEM cargo ramp.

The placard in the cockpit “MAX TAKEOFF WEIGHT 875,000 LBS” amazed me.

That reminds me of a takeoff in my C172, at gross weight and 10,000 density altitude (6,800' MSL and 90* F). During the takeoff roll it felt like someone needed to get out & push.

High DA is a triple-whammy: the engine makes less power, the propellor is less efficient converting a smaller % of that reduced power into thrust, and the wing makes less lift, so despite your reduced power & efficiency, you need to be going faster in order to fly. There's a reason those high elevation runways are so looong. The runways at Denver KDEN are 3 miles (16,000').
