I wanna see a sky diver hop out of a plane and while falling have the plane get under him and the sky diver enter the plane again while still in free fall.

Yea I like to see examples where a commercial pilot has a doubt and takes the most conservative response to keep the aircraft safe. It's easy on the .mil side since the taxpayers are not as involved as shareholders, I hate to think about the airline pilots who have to think "if I turn around and I'm wrong I might be fired."

https://www.youtube.com/watch?v=nm8iV_uiBsI This was in the related videos to the one I just posted. My god that guy's voice at 2:06 is the most pilot thing I have ever heard. Odd trivia: The AH-64 aircrew training manual actually has a maneuver designed to show off that these semi-rigid rotor limits don't exist in a fully articulated rotor head by forcing you to cyclic climb at 2+ Gs then nose it over at about 0G. Anything to make your traffic pattern a little more spicy.

Yeah. Back in the 40's and 50's there were some efforts to develop an indigenous Swedish jet engine business, though. The company working on it, STAL (Svenska Turbinfabriks AB Ljungström; these days the remnants of the business is a company called Siemens Industrial Turbomachinery) had a pretty long history in the power generation business and - among other things - built turbines for a number of power plants, both in Sweden and elsewhere. They had a working engine that they test flew on a surplus Lancaster in the early 50's, but it was too small for the Draken and the air force decided they couldn't wait for an indigenous engine and went to Rolls-Royce instead. I remember reading in some book about the Draken that the planned engine would've been better than the Rolls-Royce Avon if it had been built, but who knows, paper projects are very unreliable creatures and considering they had no real previous experience... Either way, since the air force had been the main financier of the jet engine experiments STAL got out of that business and that was that. Even if they had succeeded, though, they would probably have been swallowed up by one of the big players pretty quickly. TheFluff fucked around with this message at 04:12 on Feb 9, 2015 |

But the way I see it, same plane should be easier and not harder than one plane to another. The video showed the ability to rendezvous and fly formation with a plane to such an accuracy as to be able to get in the door. Given that, I don't see any increased challenge then getting out, flying formation, and getting back in. Unless you're talking about dropping the jumper from level flight, and then picking him back up after establishing the dive. Then yeah, that looks to be harder without a second plane pre-positioned exactly where they know the easiest maneuvering will happen from. quote:One of my favorite parts of the Wright-Patterson Air Force Museum is the 1910's poster describing how to deal with an engine failure: What do the smaller text boxes say? vessbot fucked around with this message at 07:06 on Feb 9, 2015 |

What contributed to the demise, was how the British suddenly allowed export of the Avon, thus preventing another European engine manufacturer establishing. I was told that the maintenace hatches on the SAAB Lansen are all slightly misplaced, since the fuselage was originally designed with the STAL "Dovern" in mind.

Or shutting down the engines for "reasons." Here's a brief report on a situation where a FedEx flight crew was injured during a laser illumination event on approach: http://avherald.com/h?article=48189254&opt=1 quote:A Fedex Federal Express Airbus A300-600, registration N691FE performing flight FX-386 from Memphis,TN to Albuquerque,NM (USA), was on approach to Albuquerque's runway 03 when a laser beam illuminated the cockpit causing eye injuries to both of the pilots. The crew managed a safe landing on runway 03 nonetheless. Tell your friends! Shining lasers at aircraft is a felony. They find people who do this, occasionally, and the prison times are not lenient. https://www.youtube.com/watch?v=RtKSdy2KAW4 The Ferret King fucked around with this message at 18:37 on Feb 10, 2015 |

pik_d posted:What always amazes me about this is how little distance is covered after the contact. I'm not a plane guy, but the article says Cessna so I think that's a 170 based on a bit of searching. Assuming wiki's right and I'm interpreting gross weight properly that's up to 2200 lbs, but since they were doing touch and goes it's probably not exactly running heavy. The article says it happened right as they were going back up, so they were presumably accelerating. I have no idea what the takeoff speed is in such a plane, but stall speed is 52 MPH so maybe 60-65 MPH? If we assume 2000 lbs and 60 MPH, when the plane nosed in to the ground it was roughly comparable to running a first-gen Miata in to a deep ditch and flipping over at back road speeds. I've put a small pickup in to a ditch in a kind of similar way and it came to a stop in about the same distance from impact.

Alereon posted:Have there ever been cases where pilots were actually injured by consumer laser devices, versus being dazzled and seeking medical attention just in case? In theory it should be very difficult to cause yourself an eye injury from a consumer laser held in your own hand, much less to an aircraft in flight, though of course military and industrial lasers make this easy. There are vendors selling lasers that are illegally powerful and consumers modifying their lasers to illegal power levels, but the idea that <5mw lasers (even green) can cause eye injuries to pilots (versus just being unsafe because they can interfere and distract at a critical phase of flight) seems like an urban legend. I am imagining taking an eyeball full of laser into a fully dilated pupil probably feels something like welders flash, not that I'm eager to experience it.
