The internet is telling me a 747 needs just shy of 10,000 ft to land a 747, yet Henderson Field @ Midway Island is only ~7,800 ft. Presumably during a a controlled landing with a healthy headwind the official minimum landing/takeoff number is a very padded safety number?

Midway's runway is the same size as Princess Juliana's at St Maarten (TNCM) and KLM operate 747-400s to there on regular services, so I'm guessing it's all down to weights and 10k feet is the MTOW requirement

So Topgun 2 is about drones. Sounds terrible. http://www.usatoday.com/story/life/movies/2015/06/29/top-gun-sequel-tom-cruise-drones-david-ellison/29457073/ quote:op Gun's Maverick is coming back, but he's going to be fighting a different enemy this time. Looks like they've just passed their $5000 goal for the Mustang Project, although the current owner wants $250k for it. http://www.pozible.com/project/195714 From their facebook page: https://www.facebook.com/moorabbinairmuseum?_rdr=p quote:Australian National Aviation Museum We are buying the whole aircraft, the Pozible campaign is one of a number of fundraising ventures to raise funds from different sectors. Total cost is 250k. We have the prop and engine lined up already. The aircraft itself is complete but disassembled as it has been under restoration by one individual since 1984.

Not sure how Top Gun 2 could possibly be good even if it weren't drones. "There's the enemy, 5 miles away." "Missile launched, returning to the carrier." <<roll credits>>

Just show fighters dragging to defend for 25 minutes, then head to the tanker with no one shot down. If it didn't have to be USN I'd say feature a less advanced country that still heavily relies on SAR missiles and heaters. To be fair, half the reason the fights in Top Gun were so closely pitched and cool were that it quickly devolved from a no-shoot scenario to a shoot scenario. That's still fun training with modern aircraft with the aggressors generally behaving like assholes while the friendlies try not to start a war but also defend themselves. Having long range missiles isn't super important if the fight suddenly kicked off when someone turned air policing into air combat from within a nautical mile or three.

We had a 747 land more than once on our lovely little 5500' more than once for an airshow and easily had room to spare. I'm sure a fully-laden 747-400 would have been pretty sporty though.

I'm guessing they still had 80% fuel left when they declared an emergency, then dumped a bunch of fuel? With a 747 you could land on two engines, and have the other two throttled down, already configured for reverse thrust before touchdown? Or is that too fancy for an emergency landing?

Two engines out of play for a go-around is a bad idea.

I normally don't post in this thread, but I have some stuff you all may be interested in. I paid a visit to the R&D section of the National Museum of the Air Force at WPAFB, while working on base.  This is the first time I've seen the YF-23 in person (yeah, that's the Valkyrie above it). It's just as impressive as it looks in pictures. It's kind of depressing seeing all of these really rare aircraft crammed into one hangar. There are no barriers here, so we were free to move around in and around the aircraft for a closer look. The YF-23 still has its engines mounted on it. More interestingly:  What do you all make of that metal plate above the intake, and that protrusion towards the fuselage? http://imgur.com/a/BiCXJ The YF-12 was also in this museum. It looks completely different than an SR-71 up close. The entire back of the fuselage has all of these additional control surfaces.

It must be a stealthy vortex generator. They 727 needed them in the s-duct for engine 2 to prevent an engine surge on takeoff discovered on the first flight  While searching for that picture - I found this one:

Job Truniht posted:More interestingly: I'm not an aerospace engineer (although I play one on the internet) but that looks like a vortex generator to help keep laminar flow along the side of the intake. That looks like a sharp enough bend that it could cause an eddie to form, and yeah cause compressor stall  They also go on the back of some rice rockets; Mitsubishi put them on the back of the roof of their "Evo Lancer" rally car a couple years ago to help airflow between the top of the rear windshield and the (functional) spoiler, they seem to have really taken off.

Before anybody freaks out, the F-16 is one of the best "dogfighters" in the world, so it's not surprising the F-35 wouldn't perform well against it. Some of the specifics are a bit concerning (when an F-15E pilot says maneuverability sucks, that's an eyebrow raiser), but this is hardly conclusive and no unclassified report is going to contain the actual meaningful info from which to draw conclusions on performance.

Any sane person with a base knowledge of aerodynamics could look at the F-35 and reason out that it would make for a poor dogge fighter. Those tiny wings on a heavy rear end body don't bode well for taking out an F-16.
