V-one...Rotate...This are the last words in the cockpit before a commercial aircraft leaves the earth surface during take off. After the V-one speed the aircraft must fly what ever happens. This is the critical speed, calculated at the weight of the aircraft, the power setting, runway length and weather conditions e.g. air temperature and density (altitude). Those speeds vary because circumstances vary. Average you can say that the V-one (decision)speed varies for a medium commercial aircraft (Boeing 767 or Airbus A330) between 130–155 knots indicated airspeed (150–180 miles/hour, 250–290 km/hour). Start is one of the critical flight phases but due enormous technical improvement and tremendous redundancy flying has become the safest way of transportation after crawling.
Again an experiment. On my last PP-work I received a lot of positive comments and many views. So I give it another try. Let me know what you think about it.
Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground (taxiing) to flying in the air, usually on a runway. Large transport category aircraft will usually use a derated power takeoff, where less than full power is applied, with unneeded power held in reserve in case of emergency.
After rotation (The term rotation is used because the aircraft pivots around the axis of its main landing gear while still on the ground) the nose is raised to a nominal 5°–20° nose up pitch attitude to increase lift from the wings and effect liftoff. Many aircraft will take flight even if rotation is never made, when the wings have created sufficient lift to overcome the weight of the aircraft and begin a climb, even without flight control inputs.
The speeds needed for takeoff are relative to the motion of the air (indicated airspeed). A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings.
The takeoff speed required varies according to factors such as air density, aircraft gross weight, and aircraft configuration. Air density, in turn, is affected by factors such as field elevation and air temperature. Pilots of large multi-engine aircraft calculate a decision speed (V1) for each takeoff that dictates action to be taken in case an engine fails. This speed is determined not only by the above factors affecting takeoff performance, but by the length of the runway and any peculiar conditions, such as obstacles off the end of the runway. Below V1, the takeoff is aborted; above V1 the pilot continues the takeoff and returns for landing. After the co-pilot calls V1, he/she will call Vr or "rotate" marking speed at which to rotate the aircraft. The aircraft usually lifts off within seconds of rotation. (Text Wikipedia.com)

I see you returning from your dream world. Ver nice follow up picture ;-). Very well composed, I like the experiment! Very well done.
OK, did you forget to take your medication again????
Very Nice PP work you did here.
It's good to know that they made it safely out of the vortex!
Great imagination & creativity!
Well done & TFS

Very smart your artistic picture my friend Hans.Excellent creativity.
Dizzying!! Amazing shot Hans! Very psychotic!....imagine an LSD trip! HAHAHA! Great pp work MR B!
Very cool shot. Great pp work.
Very creative and original image, your PP work very good, effects and colors great!
Great useful note, Hans! The picture is something else: I had the impression of emerging from a vortex in the Bermuda Triangle!
