Lad | One plane standing on one 3000 metres long Laufband, so big and wide as an runway. 
an Geschwindigkeits-Control setting the Laufband automatically in movement once The Räder the Flugzeugs begin To turn. and of course with the equal speed, only into counter direction.
the plane attempts to start. what happens? becomes it take off?  |

Lad | Hm, is Yes integrally neat...but I be too the opinion, that the Flugdings under remaining. the plane heave still only ex, because itself over the Flügeln one Unterdruck befindet...but if it not moving can it none Unterdruck (because of of wind) produce -> it remaining under. though schließe I with sufficient evidence too the others opinion on...

Horn | Hmmm,
if the plane really take off would:
from whom Found ought to one because nowadys still kilometerlange Startbahnen on the Flughäfen building? Why should because then The airplanes always so forever long attempt take must, until The speed to that take off access having?
One ca. 5 m langes Laufband per Startplatz for both Antriebsräder would it still then too do, or?
The Startbahnen could one then solely as Landebahnen using and so The capacity each Flughafens of now same double.
moreover had one solches 5-metres-Laufband sure in each more plane yet in the Frachtraum Space (like the Reserverad at PKW in the boot), or under. with Help this Laufbandes could then the plane of everywhere from started, where it somehow runtergekommen is (if need be too by belly landing), because obengeblieben is Yes bekanntlích yet none ...
whether The Flugzeugentwickler on The idea with the Laufband only not yet come are?
today in the PRF-course coming even the suggestion, that to the plane indeed same on the short Laufband disembark let could, because then would one The Landebahnen too yet conserve. Hmmm ... I faith, the would The inmates probably not hilarious find, as they within less sec or Sekundenbruchteile of some hundred km/h on 0 km/h abgebremst go would ...

Meier | so the plane such a thing How Auftriebskraft get, must breeze over and under whom Flügeln past wander and of course over the whole wings. with one Propeller drifting one Luftstrom solid on the trunk the Flugzeuges past. and there it itself Yes for a normales plane deal should, would the Propeller it never create, sufficient breeze on whom Flügeln vorbeistreichen To let. The Propeller should gigant his, so The breeze everywhere vorüberstreicht. with one jet would it yet worse. in front comes The breeze ungerichtet into, during tappt im dunkeln hinten aimed ausströmt. there drifting at all no breeze over The wings. it arise no Auftriebskraft. would be too To beautiful, because then bräuchten The aircraft carrier not any more so big his. one bräuchte Yes only one Laufband, position one plane on it, treibt the Laufband on, during one whom Schub the Flugzeuges increased and the plane heave ex.
rather iF. i'm time on one Laufband run. i want gladly know, where You whom Luftwiderstand hernimmst? and particularly, How should this Luftwiderstand wirken? I know me a morsel of in Aerodynamik from. but one Luftwiderstand is very the, what a plane not use can. therefore designt one one plane possible so, that little Luftwiderstand arise! |

The values in the demonstration are mere optischer nature - and so emerged! The values stand sure in keinem reference to reality!
i'll you, or. you wg. Dietmar, but nevertheless explain and so your on the Holzweg are: 
your goes in Euren Explanations of it from the itself the plane with reference to that Viewer (which not the Laufband standing!) not in the position changed! of it is nirgends The speech - integrally in the contrary: The testimony is Yes ebend the itself the plane DOCH moving, and the Laufband not more than The Radumdrehungen double. there's means none reason for the not losschießt - except for The bisl Radreibung. (radreibung is well exp to rpm, but I mean the wealthy nevertheless not the plane To break - sooner would The Achsen fall off) 
@Dietmar
and therefore is correct I you fully To, because The from you named statement is puerile.  |

GDL | the Eigengewicht the Fliegers pressing always on The Räder.the plane must always a gewisse strength spend circa these Reibungskraft To overcome.Bliebe now The speed the Bandes same would it sometime take off.there but these minimale Kraftnstrengung always through one speed the Bandes aufgezerrt.without Erdanziehungskraft went it, there then The Räder faster turn as the volume.

Rehbein | I found The question first tedious, I my, that the response slight and eindeutig is.
The Discussion shows, that the fragestellung still many confused.
1. one gear or propeller created a schub, The wings having so nothing To do !
2. from the kraftwirkung is schub the gleichzusetzen as if to the plane with a wreckers wander would
3. what could the strength entgegensetzen, that the schub (or train) To none movement the flugzeuges lead ?
4. The reibung the räder!
5. if The räder broken are would the plane as long as stand, To The haftreibung the räder überwunden becomes (with the triebwerksleistung of großraumflugzeugen sure no trouble)
6. if The räder spare turn counts it only The reibung the camp To overcome, The with steigender laufbandgeschwindigkeit always larger becomes, but sometime is tappt im dunkeln larger as The haftreibung and then slips the plane even go. The laufbandgeschwindigkeit might then gigantic his. :/:
7. the plane heave ex, if The speed the flugzeugs (to the breeze) enough big is, there then The wings whom auftrieb produce can. this erforderlichen speed standing The bremswirkung (reibung) the räder möglicherweise against.
8. plenty schub helps plenty ! 
9. starker wind of in front helps too plenty !
10. in the practice might self one laufband the itself with 1000km/h backward moving the plane not detain. 
11. the laufband could too none so quick speed go, as necessary would. it would itself self complete decompose!
