Me either. Holy sh*t that was amazing. I've watched cargo/tanker planes do some amazing things, but that blows my mind. Wow.

He had to be pretty light weight to be able to do that.

Exactly - no cargo, little fuel, max power and climb at minimum airspeed should give you an impressive climb angle.

That might be the craziest stunt I've ever seen.

I cannot imagine being there, that was scary, even after the fact.

Oddly I will say that this makes think of what an empty 777 could do.

Simply staed an aircraft is required to be able to take off at max weight with one engine out, so with the KC-10 being "light" it has way more than fifty percent more power than needed available with three engines that it can tap to create a stunt like this.

So a 772F (for example) will have well beyond twice as much power available to it with both engines working than it needs for take off. So it should be/will be an amazing take-off to see with all the power it can apply.

Of course this could apply to most any twin engine jet.

I'd be scared about the fuel system not being able to supply the engines with such an extreme climb.

Extremely impressive.

Hehe, that looks like more than the maximum 22º nose high the flight director will command on takeoff.

777 LR/F Empty = 320 klbs Thrust = 230 klbf, T/W = .719. Empty - Thrust = 90 klb
KC-10 Empty = 241 klbs Thrust = 155 klbf, T/W = .643, Empty - thrust = 86 klb

So if the take off is done at a set speed, and go 90 degrees right away, KC-10 will decelerate slower because of the difference in weight and thrust.

I don't know how thrust to weight ratio play into this equation

I know MD-11 had steep take offs, now I know if pushed DC-10/KC-10, can take off steep also.

Thank you for posting the video.

The Dutch Air Force do it as well at air shows (30sec, just after the wheels come up)

Why fast-forward to the 30 sec mark? That fly-by was unbelievably beautiful watching it in its entirety. Thanks for posting!

Well as the title of the video says, it was filmed at an airshow at Seymour-Johnson AFB in NC, so certainly the aircraft had no cargo, no pax, and not one more pound of fuel on board then was absolutely necessary for the flight. My guess is the airplane probably landed about 20 or 30 minutes later.

Very cool video though...thanks for sharing the link!

This KC10 take-off was filmed October 1991. Although uneventful, watching it reminded me of the B52 crash at Fairchild AFB June 1994. I still see the occasional news article about USAF aircraft & airmen lost to accidents while hot-dogging for air-shows. I think the most recent was the C17 crash at Elmendorf AFB June 2010 - right?

It is amazing & impressive to see - and I know these guys are supposed to know what they are doing (flying tankers & bombers like fighters) but it is tragic when things go wrong and folks die.

Performing a high AOA takeoff like that...looks great, but the last thing you want to happen, is an uncontained engine failure.

Uncontained or contained, either way you're screwed. The engine failure would be the problem, regardless of containment.

Not sure if this is the best idea with the 777. I wouldn't want to find out there wasn't enough rudder authority to compensate for that level of asymmetric thrust in an already mushy handling scenario.

Wow! - I think for the first time, after watching many youtube 'hey look at this insane pilot taking off with a 5kt crosswind' clips, we really have found one that genuinly is! Mad as a hat. Fantastic!

Since it's referred to as an airshow takeoff, and there seem to be quite a few videos of such takeoffs, I'm guessing it was fairly routine at air shows.

Very impressive! Just by looking at it, I imagine they had no cargo/min. fuel. I would not want to be sitting up front if one of the engines quit though.
