I was watching a movie recently (the title is slipping my mind) and there was a scene with a business jet that was climbing vertically. I made the comment that it was impossible for a consumer level jet to perform such a task due to their low thrust to weight ratio, and the lack of rigidity of their airframe. I'm fairly confident that a business jet can't produce enough power to overcome its own lift and the force of gravity, and even if it could, its airframe would suffer catastrophic failure. I then furthered my argument by stating that some jets are able to CLIMB vertically, but to my knowledge there is only one jet that can ACCELERATE vertically: the F-16, due to its thrust-to-weight ratio greater than the value 1. Am I correct in every aspect of my knowledge? Can business jets CLIMB vertically? Can business jets ACCELERATE vertically? Are there other jets besides the F-16 that can ACCELERATE straight vertically? Easy 5 stars.... Thanks for the help!!!

Minootoo, I believe that you are confusing the terms CLIMB and ACCELERATE... Some propeller driven aircraft can climb vertically for a short period of time, but I assure you that no propeller driven aircraft can produce enough thrust to ACCELERATE vertically. If you are still confused I will be happy to explain.

I'm not referring to VTOL. I'm talking about jets that can accelerate on their native trust axis perpendicular to the earth's surface (i.e. the force of gravity)

F-16
F-22
Most jets with RR engines can do a tail stand.

OK, you defined the question much too loosely. It is very easy to achieve vertical accelleration from both normal jets and piston craft by using the lift characteristic of the wing. Any craft that cannot accellerate in a vertical plane is very useless, it would never "get off the ground" so to speak. A common rotary wing craft (heliocopter) can perform a true vertical lift. Granted, most craft use a less than vertical approach to gaining altitude in normal operation, but your contention that thrust to weight ratio must be greater than 1 only applies when thrust is the only component contributing to lift.

Most Jet plain can, or even propeller plain can.
But.
It is very dangerous, if the plain is not strengthened for air acrobatics and pilot has no training, and or experience in air acrobatic.
Plain is also fitted with a larger heavy duty engine to pull the stunt off. Takes lot of, power, skills and the nerve.

Why would a business jet accelerate vertically? Even if they could it would not suit their purpose as they are built for comfort not to engage in dogfights. I don't think Donald Trump would take kindly to his pilots if he ever tried to drink whiskey and his pilots decide to do a tail stand

VTOL, Verticle Take Off and Landing.
They've got a lot of different jets listed on wikipedia.

F-22 can break the sound barrier going vertically.

While _most_ propeller aircraft can't accelerate vertically, a (very) few can http://www.rapp.org/archives/2007/09/turbine_toucan/
