Status: offline 		The Discovery Channel recently decided to crash a radio-controlled 727 to gather valuable scientific data. To fly the monster aircraft, the team they contracted with selected the Futaba 8FG.

Watch this epic event unfold this Sunday, October 7, on the Discovery Channel at 9:00 p.m. Eastern Time (8:00 Central). Check your local listings for details. Until then, you can read more about the team that pulled off this amazing flight at the link below — see pages 8 & 9.

Not stand around  wondering if they would loose their link at take off, just after, or any time thereafter.

Why is it so hard to believe that our systems are capable of sending a signal to the appropriate actuators?

I have my DVR set already to record the show. I will hold my opininons 'till AFTER i see the entire show.

You are foolish if you do believe it. They should be arrested for endangerment if they are. Our little 100 MW signal could easily get lost in that metal skinned aircraft. They are probably on 900MHZ with 10w at least and are using circular polarization.
I was the system engineer at Goldstone tracking site for the Lunar Orbiter space probe. We could get reliable transmission to the moon with 2W but we had a transmitter antenna gain of 54 db and our receiver had a cryogenically cooled MASER( like a LASER but used RF instead of light) preamplifer

they did not use a stock receiver either.

door opening  could easily be overcome by aircraft mechanics.

The rear air stairs on a 727 go under the tail not out the side.

I have never had an issue with Spektrum since it was first introduced. Most of our 110 member RC club is on Spektrum. It is a reliable radio system.

Who said anything about the side?
It would be impossible to go out the side. The stabilizer would make chopped meat out of you.
You would have to go out that under the tail door. Even so you wouldn't get far down those stairs in that wind. I really doubt you could get out without hitting something.
You would have to take those stairs and the door completely off and have an open space to jump into. Even so that 200 mile wind will be a sever shock when you hit it. I doubt many would survive.
Paratroupers jump out the back of their airplane but they are well conditioned individuals. You see them jumping out the side but the airplane has dropped down to a very slow speed. You can't slow that 727 to much below 200mph

Right. But you won't fly very long at that speed. And that is with the wheels down and flaps deployed. It wouldn't be very smart to jump out and leave the aircraft in that condition.

dirtybird, you are a long time modeler, some 66 years, however you have many misconceptions concerning the Boeing 727. I have not paid much attention to the 727 "Crash" but sometime ago, soon to be 17 years, I set the parking brake for the last time and left my old friend, the 727. During 28 years of airline time, the 727 was my main machine, in 4 versions, having some 12000+ hours there in all positions, 2nd Officer, First Officer, and Captain. Those times were interspaced with times in the 737, DC-8, and DC-10.
Yes you can slow a 727 considerably below 200 mph. You do not have to have the landing gear extended to have the flaps down for lower speeds at various flap extensions. Below flaps-25 you get a horn blowing if the gear is not down, but a circuit breaker can silence that. The rear stairs can be used as an escape door. The horizontal stabilizer is very high on the vertical stab and would not be a problem. OTOH, engines 1 & 3 just may well be such for a side jump!!! Approach and landing speeds were a function of weight at any given time.
BTW, I had a couple years in the USAF C-123, a fun machine, and deployed paratroopers many times, all out the back.
