"Decision speed" (V1) means you have to decide wether or not to takeoff. If you elect to takeoff (V2), any emergency (ie, engine failure) becomes an inflight emergency.

Actually, V1 is decision speed (meaning, in the event of loss of an engine, for example, it is the better option to continue, if above V1).

Vr, is rotation speed.

V2 is the MINIMUM safe climb airspeed......

Bastard! You beat me to my joke. You get the Leitendernoseandfart joke award for the day!

What Doug failed to mention is that V1 also refers to the point at which the A340 has to think about rotating after using 10,000 feet of runway and avoid hitting the fence at the end of the runway.

Gotta love the A340 jokes with regard to power (or lack thereof!)...keep 'em coming!

Of course there is V2 SOL up here in Aspen, when you lose all power on your climb out and visibility is 1/4 mile and the ice on the wings is getting pretty thick, and the cockpit windows are fogged up so you can't see the nose. Yep, been there done that.

Important safety tip, no matter how much they charge for glycol, pay it. Never can use enough.

The rocket was the V2, the V1 was a pulse jet powered cruise missile known as the doodle bug, they were not immune to interception, one tactic being for a fighter to tip the wing with it's own wing to cause it to crash, a lot for shot down by AA too, whereas the V2 was beyond any form of defence other than preventing it's launch.
