I got to tour one of the last flying Skyknights, a contractor flown US Army test support (White Sands) aircraft based at Holloman AFB in the late 80s. It was a big airplane, with huge electronics bays. The amount of instrumentation installed in the a/c was very impressive.

The discussion started when I declined to allow them to buy my drinks due to DoD regulations against such things. Their stories were nothing on the scale as discussed in the article, but much smaller potatoes meeting the "expectations" of (primarily) Middle Eastern and Asian types visiting them in the UK. The standard stuff you'd expect, wine, women and song for the most part, but some of the visitors had very unique requirements. The funniest was a senior military officer from an unnamed Middle Eastern nation who wanted to drive a classic Aston Martin. They made it happen, but the VIP was very disappointed the car lacked all the high tech gizmos and systems on James Bonds' car.

Quote from: Walks_At_Night on October 26, 2017, 08:48:36 PMI wonder if the proposed Dam Busters remake will ever happen?
Quote from: albrecht on October 26, 2017, 08:58:29 PMWhy? An almost perfect movie already. Hollywood is only about remakes and they, usually, are worse than the originals. Then again, I guess it would be nice for kids to see the events. And with a good director, real planes (and not CGI crap,) it could work. Obviously, the dog will be renamed for the audience's sensitivities.

QuoteThe project is given the code-name Rescuer and will be handled by Alekseyev Central Hydrofoil Design Bureau, which in the past produce ground effect vehicles such as Lun and Orlenok.The vehicle is expected to weigh 600 tons with a length of 93 meters and wing span of 71 meters. It will be able to operate on land as well. Top speed is 550 km/h.Scaled models have completed wind tunnel testing and the timeline to complete the project is 2025.
Quote from: Rix Gins on October 29, 2017, 12:43:24 AMReally, a bird/birds caused this damage? Looks more like a cannonball hit the plane. http://www.abc.net.au/news/2017-10-29/nba-oklahoma-thunder-stunned-by-major-plane-damage/9097020
Quote from: Taaroa on October 29, 2017, 02:54:09 AMI may be remembering things wrong, but an airliner nose cone is made of lighter and weaker materials (eg fibreglass) to allow weather radar beams to pass through with less interference. You have to remember also that the plane is traveling very fast at that height - say for argument it's doing mach 0.8, at 30000ft with standard temperatures it'd be doing the equivalent of 541mph - and even a goose will cause a lot of damage.This pic is from hail damage:
Quote from: Uncle Duke on October 29, 2017, 08:50:54 AMThe key to birdstrike damage is the airspeed of the aircraft at the time of impact. If you remember your basic physics, the velocity term is squared when determining kinetic energy, so even a small bird can pack a lot of punch in a collision with an a/c at high speed. The first B-1 we lost was as a result of a strike by a pelican, basically punched a hole in the aircraft and took out key systems. We lost three good men in that mishap.https://www.washingtonpost.com/archive/politics/1988/01/21/air-force-blames-pelican-in-fatal-crash-of-b1b/62d03249-691c-44ec-95d6-a7200d2f1159/?utm_term=.51071d623396Birds are also particularly dangerous when they get ingested into jet engines. They can take out turbine blades that take out more turbine blades and things go to shit very quickly. That's what happened when Capt Sullenberger had to put his airliner into the Hudson River.

QuoteA Virgin Australia Boeing 737-800 performing flight from Melbourne,VI to Brisbane,QL (Australia), was climbing out of Melbourne's runway 27 when the crew declared PAN reporting excessive left hand engine vibrations and decided to return to Melbourne. The aircraft levelled off at 5000 feet. The crew advised an eagle carrying a rabbit had just impacted their #1 engine, positioned the aircraft for an approach to runway 16. The aircraft landed safely 17 minutes after departure.
Quote from: Taaroa on October 29, 2017, 11:26:20 AMIt's one of the reasons why airliner engines have the marks (swirl etc) on their spinners - when they rotate at engine speeds they flicker in some kind of way that is meant to scare away birds. https://youtu.be/_Xb4c_KqLco
Quote from: Uncle Duke on October 29, 2017, 05:23:05 PMI never knew that, I always thought it was just to look cool. It would be interesting to see effectivity data on the spinner markings, seems like the aviation equivalent of automobile mounted deer whistles. I remember a bird strike on a commercial airliner above 35K ft, maybe 20-25 years ago, involving a large soaring bird like a condor. It was either in South America or Africa as I recall.I know of at least two "boar strikes" on take off involving F-16s over the years. One involved a USAF a/c, I think in South Carolina or Arkansas. Don't recall there being any injuries (except to the boar), with limited damage to the Viper. The second incident occurred in Pakistan and was said to have destroyed the a/c, no mention of the fate of the pilot(s). The Pakis, as well as the Israelis and a few other nations, did not release information on aircraft lost in mishaps even to the USAF Safety Center. We eventually heard about them, but seldom got any details through official channels. The Israelis were particularly annoying, they expected us to provide mishap data and technical support at the drop of a hat, but getting anything from them was like pulling teeth.
