Crazy take-off (Boeing 787)

[Phoenix86]

dat thrust

Bricks are aerodynamic enough with proper thrust. :awe:

Meh, not so crazy. Pretty sure military cargo planes pull similar maneuvers all the time so as to make harder targets for ground fire.

Yeah, but they do it LOADED. Fuel, cargo, people.

I suspect they are riding the edge of safety more than this plane was.

i woulda crapped my pants if i was on that flight.

I know other planes can do that as well. But still, that was impressive.

789 is somewhere around 300,000 lbs operating empty weight. i'm assuming they didn't load it up with fuel for doing demonstration flights, so i'm going to ignore that. thrust is about 150,000 lbs. that's a thrust to weight ratio of about 1:2. the empty weight of an F-86 sabre is about 11,000 lbs (operating empty weight is empty weight ++, so you can fudge that upward some). thrust was about 6,000 lbs. so, the 789 isn't far off the thrust to weight ratio of a korean war fighter plane.

And there's the reason why it could do that, a LOT of MTOW is fuel weight and clearly he had just enough for the show plus no passengers or luggage weight either. My guess is he he held off on Vr for a few extra seconds as well to generate more speed before finally rotating and then if you watch closely he noses over to close to a level altitude fairly quick before his airspeed drops too much.
