Energy management.
Light load, lots of thrust and speed, no problem. The master of energy management maneuvering would have to be Bob Hoover. |

There's no way he's gaining speed as he goes vertical, you can tell by the video.

A test pilot once rolled a 747.... BzzzzzTTTT!!! WRONG!! It was a Boeing 707, the Dash 80 that was rolled by Tex Johnson. http://www.youtube.com/watch?v=-vHiYA6Dmws The story after the 707 "DASH 80" Barrel roll... The plane lands at Boeing field and Tex gets out and starts to walk away from the plane. A Boeing official runs over to Tex and tells him Mr. Allen wants to see him now. Mr. Allen is the president of Boeing. So Tex heads off across the street to the Boeing Exec offices and into Mr. Allens office. Tex walks in. Mr Allen from behind his desk says "How are Tex...Hows the family"? Tex answers the boss. Mr Allen the says "I hear you rolled the plane today, Tex". Tex says quietly....."Yes sir I did". Mr Allen answers..."Don't do it again.......Bye Tex..say hello to the wife..". About the Aircraft... The Boeing 367-80 was the name of the "prototype" of both the 707/720 commercial transport/military transport/military tanker/military communications plane and the 717/739 (KC-135 etc) military transport/tanker. It was called the "Dash-80" and although 707 was eventually written on the tail (and it was registered N70700), it wasn't really a 707 so much as a pre-aircraft, a basic-built demonstrator. -The 707 and KC-135 look similar but beside different lenghts, have different upper fuselage lobe dimensions (ditto for the Dash-80) and different alloys. -The Dash-80 was flown in August 2003 to Washingon, where it has been permanently retired to the big new annex of the Smithsonian's museum of air and space. Here it resides with Concorde and many other important aircraft. -Tex Johnston did the barrel roll and even if test pilots back then were different, the company was stunned by it and whatever the exact conversation was like, he apparently came close to losing his job. But the roll seems to have impressed the military and to have gotten Boeing the large contract for the KC-135. |

Cathay Pacific pilot fired for 'Top Gun' tactic Posted: February 26, 2008, 1:36 PM by Scott Deveau Transportation A Cathay Pacific Airways pilot has been fired after he performed an unauthorized "fly-by" with the airline's chairman and 60 other VIPs onboard, according to a report in Flight International. The incident took place on Jan. 30 shortly after Cathay took possession of their new 777-300ER from Boeing in Everett, Washington. After takeoff, Captain Ian Wilkinson brought the aircraft around again to the airfield and made a low-level fly past with the plane's wheels up - a maneuver that requires approval from the flight control tower, which the pilot failed to secure in advance. The Top Gun-style fly-by, which apparently brought the plane within 8.5 metres of the runway, was caught in these photos and on this video. |

757 are race horses(imo) Depending on what type of engine they have on them, (GE, PW or RR) the PW normally has 40,000lbs of thrust for each engine. Unless its de-rated like Deltas 757 which are 37,500lbs of thrust for each engine. Thats alot of power for a narrow boby A/C
I loved flying and working on those. They are my favorite |

There's not a single plane in the world that's certified safe to fly in commercial passenger service by the FAA that can't safely perform a Chandelle, a roll maintaining 1 G positive through the entire maneuver.
A 707 can do it. A 747 can do it. A 737 can do it, a 777 can do it, and the 787 will be able to do it. Every Airbus can do it, from the A300 to the A380. It's not as demanding a maneuver as you'd think. And the plane doesn't even have to be prepped for inverted operations as long as you hold positive Gs on the airframe by applying suitable back pressure on the controls during the maneuver. I'm quite sure that a lot of airliners have made landings that were more stressful on the airframe than a basic 1 G Chandelle. Rumors persist about a retired Eastern Airlines pilot who, on his last flight prior to retirement, got to hand pick his entire crew for that flight, and he picked people who know how to keep their mouths shut. The story has it that at some point during this flight, a regular passenger flight, he rolled the plane. Why not? It was a safe maneuver and all they could do was ground him. Since this was his final flight prior to retirement anyway....seize the opportunity! I truly can't remember if it was a 727 or a 757 that he rolled, but I think it was one of the two. CJ |

when they don't have a load of passengers, cargo and all that fuel, they can fly like you wouldn't believe. I haven't gone vertical, but I've seen an awesome ROC |

FWIW- An airliner, or any other airplane, does not "know" it's vertical, or even upside down. The 757 has excellent power to weight ratio, and that one was hauling ass at the start of the pullup. It looked to be at about 85 degree pitch toward the end of the clip. You would get annoying warnings, but as long as you fly smooth and watch the AOA, there is nothing inherently dangerous or difficult about that particular maneuver. There is not an airplane made, that couldn't do it, at least for a short time.

If you made sure you were very slow at the top, then pull to idle, and throw out the speed brakes flaps and landing gear, you would have a fair chance of pulling out before the wings and tail separated. I would try it for 3 million. Let me know if you have any billionaire friends who want to make a cool video. |

That first vid in the OP was of a New Zealand Airforce jet.
They do that at all the airshows we have here, it's pretty much the only jet action the RNZAF has to offer, I’m lucky I got to this country before they killed the combat jets and was able to see a few shows with the A4’s, those little jets were very impressive. Earlier this year, in March I think we were very lucky and we had a USAF C17 at the show, WOW, talk about impressive, the Aussies also brought in two F18 Hornets, was nice seeing / hearing a high performance jet again. But that 757 is very good, the RNZAF don’t have too many cool toys, but they sure as hell know how to play with the ones they do have, that’s for sure, and yes, near the end of the climb out that 757 does look VERY near vertical in real life too. If anyone is interested I’ll post some of the air show pics when I get home from work. |
