- inactive, on 12/13/2008, -6/+86That doesn't seem that hard.
All you have to do is press Z or R twice. - spritom, on 12/12/2008, -2/+65The answers seem right in line with what little I know on the topic. Commercial aircraft could basically do any aerobatic maneuver, though there are issues such as stressing the airframe past its design limits or fuel pumps not getting enough fuel to the engines while upside down, etc.
also FTA:
"to put it mildly, but a jet will not -- repeat, not -- "fall," "drop," "plummet," "spin," "plunge," "nose-dive" or otherwise come flailing out of the sky like a pheasant full of buckshot." - Jektal, on 12/12/2008, -0/+57Wow, that's actually a really cool read!

- shibainu, on 12/13/2008, -4/+43On March 3, 1969 the United States Navy established an elite school for the top one percent of its pilots. Its purpose was to teach the lost art of aerial combat and to insure that the handful of men who graduated were the best fighter pilots in the world. They succeeded. Today, the Navy calls it Fighter Weapons School. The flyers call it: TOP GUN.
- Jektal, on 12/12/2008, -4/+42Do a barrel roll?
- Zomgondo, on 12/13/2008, -5/+40DUH jets can do acrobatics... some pilots use them to shave seconds off the schedule:
http://www.transmogrifier.org/ch-img/ch880515.gif - k3rfuffl3, on 12/13/2008, -0/+29I dugg your comment for two mutually exclusive truths.
- cslawren, on 12/13/2008, -5/+31Maybe I'm an arrogant ass, but these answers seemed blatantly obvious.
- GlassAgate, on 12/13/2008, -0/+25"This is your captain speaking. Please make sure that your
seat belt is properly fastened, as in the seat belts of the people
next to you. I'm going to have a little bit of fun here. Enjoy
the spin." - inactive, on 12/13/2008, -2/+26Actually, I always leave the youtube comment box collapsed.
If I don't, I might get some stupid on me. - beerhound, on 12/13/2008, -0/+20The F-16 was the first fighter jet to enter service with a fly by wire flight control system. There is no direct connection between the pilot's control stick and the flight control surfaces. The pilot moves the stick, a signal is sent to the flight control computer which interprets that movement and then sends a signal to hydraulic actuators to move the control surfaces. Electrically there is a "main generator" and a "stand by generator" that are engine driven. Hydraulically there are "A system" and "B system" pumps that are engine driven. If both of those generators, or both hydraulic pumps fail or the engine quits and stops spinning (I say "stops spinning" because airflow through the engine while the aircraft is gliding still spins the engine and drives the gens and pumps enough to make some power) then the emergency power unit kicks in and spins an emergency generator and emergency hydraulic pump for about 10 minutes. After the EPU stops, there is still a separate battery to power each of the flight control system's 4 redundant channels and a couple of fairly large hydraulic accumulator to supply power for a limited time. The F-117's flight control system is based on the F-16s, but I can't give as much detail on it as I signed a 75 year non-disclosure agreement when I left that program. Come see me in 2073 and I'll tell you everything I can remember. Hint: I'm 43 now so you might have to knock REAL LOUD for me to hear you where I expect to be residing. My point in all this is that there is an ass-load of systems redundancy built into these things and newer commercial aircraft are far safer than any military aircraft (but they don't get the cool addons like missiles, bombs and lasers). It takes far more than a couple of simple failures to take them down. I have seen many more cases where the pilots were the cause of a smoking hole than systems failures, but I will still shake their hands every time they bring one back after it all "goes to hell".
- RuyGuy, on 12/13/2008, -0/+18It's so annoying when people think if your engines quit you "fall out of the sky."
- EagleTG, on 12/13/2008, -0/+17Did you all check out this guy's (the author's) Flickr stream? Some of the shots are absolutely amazing. A link for the lazy...
http://www.flickr.com/photos/globetrodden/ - Mitchl, on 12/13/2008, -0/+13During an attempted hijack of a FedEx flight in 1994, a DC-10 was flown inverted to help the crew gain control of the attacker. (FedEx flight 705). It was both fully fueled and fully loaded, and the plane while damaged during some of the manuevers and during the landing still flies for FedEx.
- maximilen, on 12/13/2008, -0/+12The Concord (oversized and under-armed fighter jet) can, er could, easily do barrel-rolls all day :) Shame it's gone...
- verevi, on 12/13/2008, -0/+12What about for the super lazy? Will you come click that for me, please?
- angryfirelord, on 12/13/2008, -0/+11SLIPPY GET BACK HERE!
- EtherGnat, on 12/13/2008, -1/+12"Barrel rolling is not used exclusively in aerobatic competition. Both the Boeing 707 and Concorde prototypes were barrel rolled during testing. The 707 was rolled just once by Tex Johnston while Concorde was rolled multiple times by her test pilots, including Jean Franchi and Brian Walpole."

- RuyGuy, on 12/13/2008, -0/+10You can roll just about any plane. Not that big of a deal. You cant however, keep every plane upside down for very long.
- onelikeseabass, on 12/13/2008, -0/+10Jets cannot perform acrobatics. They can, however, perform aerobatics.
- usafdave, on 12/13/2008, -2/+11Wrong. A barrel roll is the equivalent of driving a racecar up the edge of a tubular track, up and over, then back down the other side (psst... like in teh videogamezz)... while it may appear as though he just performed the wingtip-over-wingtip, often misconstrued as a "barrel roll" by the public, if you watch the end of the vid first, where the clouds actually give you some spatial bearings, you can see that he did indeed perform a true barrel roll. Second video confirms... "1G maneuver... no hazard".
Besides, a 707's wings wouldn't take an aileron roll... *SNAP*, *SNAP*... *****, now I'm an airborne ground-torpedo! - cankillar, on 12/13/2008, -0/+9That barrel roll wasn't scripted- He was supposed to do a flyby to show it's massive transportation abilities. He did it once, then turned around and did it again, just to make sure everyone saw it.
In a recent Seafair he was commissioned to fly one of the last working 707's again- this time with an air marshal as his copilot. - CamperBob, on 12/13/2008, -0/+8I can't imagine the kind of personal restraint it must take airline pilots to keep from rolling their Boeings on their last day before retirement. Guess if they get fired, they lose their pension.
- spritom, on 12/12/2008, -1/+9The article doesn't get to the "upside down" part until page 2. But like you have in the videos above, Tex Johnston rolled a 707 in early testing. I wonder how many times Tex said "Goose, it's time to buzz the tower" in his flying career. The article also mentions Bob Hoover who did amazing aerobatic stuff with smaller passenger jets.
- Reiben, on 12/13/2008, -1/+8Its almost like we need some sort of technology that can store power... If only.......................
- RuyGuy, on 12/13/2008, -0/+7You fail. Of course a C-130 can do a barrel roll. My brother flies them for the Air Force and according to him, they can.
- HappyScrappy, on 12/13/2008, -0/+6If you do a 1G barrel roll like with the 707 above, the G forces are 1G in the "downward" direction (toward the the wheels) on the plane, and thus it doesn't even know it's upside down. So it won't break apart.
If you didn't ensure to maintain a 1G in the "downward" direction like this, it's possible the fuel system wouldn't do a great job of getting fuel to the engines, and they might stall after a while. - Enasni1212, on 12/13/2008, -0/+6I don't see why this is so strange to you. It doesn't make sense to anyone with even a high school understanding of physics... but how many people actually have/retain that?
- pinguwin, on 12/13/2008, -0/+6I fly hang gliders and a low-end HG, has a glide ratio of about 10-1, approximately the same as the jet described in the article. 3000 feet of altitude means that I'll get about six miles of horizontal before landing. In theory of course, YMMV.
- poordavey, on 12/13/2008, -0/+6Use the boost to get through!
- SniperGX1, on 12/13/2008, -0/+6if you were a passenger on a 1G maneuver and had your eyes closed you wouldn't know you just went upside down
- proliance, on 12/13/2008, -0/+5Bob Hoover is the man!
Hoover is one of the greatest natural pilots ever, and that's not just my opinion, that's Chuck Yeager's also. Hoover was stuck as a test pilot for much of WWII and didn't see much combat. When he finally did, he shot down three German planes on his first real combat mission, but also got shot down in the process.
What I remember most from his autobiography is that he managed to escape from a German POW camp, STOLE A GERMAN FIGHTER and flew it to freedom. His balls are the only part of his body larger than his nose.
I've seen him fly at a couple of airshows in his Shrike Commander, and he always flies in a business suit. He is a Nashville, TN native, and I plan on starting a campaign to name the city's airport after him soon. - blackjack06, on 12/13/2008, -0/+5http://www.youtube.com/watch?v=S61zLcMFp1A&fea ...
- tgc1, on 12/13/2008, -0/+5You forgot the part where everybody screams in terror. Except for the Captain, who's laughing his ass off.
- MaruLono, on 12/13/2008, -0/+5FOX! GET THIS GUY OFF ME!
- Frost9999, on 12/13/2008, -2/+7Concord test pilots did barrel rolls in them easy peasy.
- ChloeMS, on 12/13/2008, -0/+4Aside from airframe stability (the forces acting for lift for example) the fuel system would have to be designed so that fuel could be pumped from the tanks while the aircraft was upside down. All aerobatic aircraft have this design feature. Most commercial aircraft do not. This does not necessarily prevent a complete roll however.
An for the comment about a AC-130 not being able to roll, that person has obviously never seen a Spectre or 'Spooky' maneuver! - milkmage, on 12/13/2008, -0/+4except for the VIDEO where they ***** do it (see above)
thanks for playing. - mastaphoo, on 12/13/2008, -1/+5FOOOOOOOOOXXXXXX!!!!!!!!!
Digg me down if you want, I couldn't resist. You know the urge is inside you, too. - aseriesoftubes, on 12/13/2008, -0/+3Not even helicopters 'fall out of the sky' if their engines stop. I'm no pilot but it's apparently possible to 'glide' a helicopter and perform a 'hard landing' which means you come down with rotor being turned by its own remaining momentum and by the air itself as you descend.
I heard about this in safety briefings when I started flying in dodgy old Russian military transport helicopters in dodgy places. Even if the pilot gets it right and you're not starting too high you don't necessarily walk away afterwards of course... - Disgod, on 12/13/2008, -0/+3It was a gentle, gliding descent... until the landing. He never said anything about the landing being gentle.
- spyd3rweb, on 12/13/2008, -1/+4No you must not question the LORD your government.
- wondertwins, on 12/13/2008, -0/+3i saw that coming a mile away
- Mossman85, on 12/13/2008, -0/+3I have a question for the pilot. What did he choose between fish or steak? I myself had lasagna.
