I trotted out this explanation to him (decades ago) and he bought it.
Well it's true ! :-)
The B-26 Marauder ( WWII bomber ) had close to maximal wing loading. Not good for new pilots though, who would throttle back too much after take-off and readily stall at low level with often fatal outcome. Experienced pilots who converted over thought it was a great 'hot rod' but needed handling with care.
Cheers, Mike.

My standard speech when my train reaches the east end of track: This is the east end of our railroad, a place we call Kishwaukee Grove. That's because there's a bunch of trees in front of us [point them out if they're visible]. Behind them is the Kishwaukee River. We don't have a bridge over it, so this seems like a really good place to stop. [This usually gets a laugh.]
This seems like a really good time to go to sleep.

Why, yes for up and down vectors. For wind-shear headwind / tailwind vectors things get a bit more interesting and deadly.
When going from tailwind to headwind, mass of the airplane is going to be the bigger factor. But this direction isn't the dangerous one.
Going from headwind to tailwind, that is the deadly direction. Mass plays a part, but thrust to mass ratio is what matters as does how fast you can change thrust. This is where a Cessena has it over a jumbo. That gasoline prop job can go from zero to max just about as fast as the pilot can advance the throttle. Jumbo's not so much.
Then again I saw a guy in a Stearman with a negative ground speed once. Yes, it was a windy day.
Interesting reply Archae86. I was also amazed at the difference head and tail winds make. On the outward trip we cruised at about 550mph with a headwind, an the way back we hit 625mph with a tail wind. The A380 cruising speed is 565mph. I took a pic of the screen on the back of the seat in front if I can find it. Someone said to me the tail of an aircraft always wags more than the front does, like a dog in a way, which is why Business and 1st Class are up at the front. I always thought it was because they could get off first after landing.
But geographical features matter as well, leaving or landing at Vancouver entails going over the Rockies a notorious place for air turbulence. We hit it coming back from Fort St John to Vancouver, and again not long after take off to London, and about half way across Canada.
Yet on my previous trip to San Francisco I flew out on a 777 and back on a 747, both legs as smooth as anything.
Waiting for Godot & salvation :-)
Why do doctors have to practice?
You'd think they'd have got it right by now
Would it trigger a win if I worked "sasquatch" into a post? Sasparilla? Cabernet sauvignon? A left toin at Albukoique? All of the above in a single post?
Nope, but closer than most in one of those. Keep in mind the thread title.

I am relieved to hear it, Sir, and heartened it has not been refuted. ;-)
@Mr, S
Good day to you :-)
I trust that you enjoyed it to its full potential, and landed safely. Trouble is that these days not many people have their feet on the ground.
Keeping the tail of the craft out of the ground was a little more challenging than I was prepared for, Sir. That my instructor earned his fee is all I am prepared to divulge further. ;-)
I think my brother got some eggbeater flying lessons too. He said something about having to do separate things with his hands. You know, to get it up and and back down. similar to patting your head whilst rubbing your stomach. I'm actually quite good at that, so.... *raise one eye askance in fashion of getting a good idea* maybe it's something I should consider.
I just came back, people. I forgot to say hello :)
...and again to say I'm not sure what happens when going forward though. I suppose you find that out after you're off the ground. It wouldn't be much use before.
Please wait here. Further instructions could pile up at any time. Thank you.
Oh. The forwardy/backery/lefty/righty/uppy/downy stuff. Apparently it will do that anyway. I believe the trick is to get it to do that in, for example, a non-random sequence.
Cheers, Mike.
