DC-9 "Emergency Escape Chute" Deployment? Thoughts?

Hi all: I stumbled upon some video of the DC-9 during flight testing, and noticed something pretty amazing. I wanted to get your thoughts. Here's a GIF showing what it is: https://media.giphy.com/media/xUPGcKtg8p2vy2NezS/source.gif If the GIF above doesn't display, here's the 19sec video itself (sam...

Haha, that's a funny story.

Sound, sound waves, I was just differentiating the light LIDAR uses vs guns governed by the FCC.

Is it legal to aim police LIDAR/LASER gun at airplane to measure speed?

Hi all! Do any of you know, or could you help me find out, if it's legal (or illegal) to aim a police LIDAR/LASER GUN at an airplane taking off or landing at an airport in the US? LIDAR/LASER guns are different than RADAR in that laser guns use light to measure change in distance, while radar uses s...

Re: JT8D variants for MD80/Super727 - need opinions!!

I pulled the GeminiJets engines off of the MD80 and put them on a 727 to give me an idea of what it would look like. Is it just me, or are they WAY too big? http://i68.tinypic.com/2yjwzep.jpg http://i67.tinypic.com/3095v6u.jpg http://i68.tinypic.com/jj48yu.jpg

JT8D variants for MD80/Super727 - need opinions!!

Hi all: I need your input and specs for the JT8D engines on the MD80 and Super 727. I collect 1:400 aircraft models, and am in the process of converting a regular 1:400 B727 to a Super 727. To do this, I need to swap the #1 and #3 JT8D-100 engines with JT8D-200 engines from the MD80. I need a 1:400 ...

Re: B727Adv with JT8D-217 engines--what about reversers? 3 Questions for you all. Thoughts?

Does that mean they had to install a new hydraulic line for the #1 and 3 reversers? And why wouldn't they just leave the #2 pneumatic reverser as it was? Why remove it? Weight? If, for instance, the #1 -200 engine were to fail, could the #3 -200 reverser alone produce the same reverse power as the #...

Re: Possible B727 Vintage Artifact?

So here's an update. I found out some more info about who owned it before me. Anyone have thoughts as to how it might have gotten into civilian hands? I also just realized that the tail number on it is N72700 which is the second 727 to be produced. Not the first. Do you know if the first 727, N7001U...

Possible B727 Vintage Artifact?

Hi all: Not sure if this is in the right section of the forum... but, I found a possible 727 artifact in an estate sale and was hoping that someone on here could provide some information on it. If this artifact is significant, would it be something the museum of flight (who currently has the #1 727 ...

Boeing 707 With "tail-mounted Engine? It Existed!

Hi all: I wanted to share something that i thought was interesting, and want to get your input. We've all heard of B747s with a 5th engine, L-1011's with a 4th engine, etc but they've always been 'inoperative', just hanging there for the purpose of transporting for maintenance. I stumbled on this im...
