It might be this plane she jumped from, a DC 9 not a 727 - similar but a bit smaller.

I wouldn't be surprised if it featured on the documentary. Assuming the 727 pilot is an experienced skydiver, it would still make sense for them to take a few practice jumps from the DC 9 to familiarise themselves with jumping out the back of a jet airliner.

I call bullshit on the word "ejected". Installing a seat would be a massive amount of hassle - cutting a hatch in the roof of the cockpit would be a major modification of the airframe. I'm no airplane geek but I bet the airframe would need FAA recertification after that kind of modification, plus a massive amount of testing to make sure it all worked correctly (you really don't want the situation where the seat fires but the hatch remains locked in place). I admit I'm pulling a number out of the air, but I'd be unsurprised if there was little change from ten million.

Forget the ejection seat. I bet the reason they used a 727 is that it's fitted with an Airstair, a combined hatch/stairway at the very rear of the aircraft. The Airstair makes the 727 one of the few airliners that it's possible to parachute from without the risk of being hit by the engines, wing or tailplane - a person known as "Mr Cooper" proved this was possible in 1971. The only modification needed to do it again is the removal of the Cooper vane, a small aerodynamic device fitted to 727s after the DB Cooper hikack, intended to stop the Airstair being opened in flight.

I have had the pleasure of seeing-hearing-feeling a Spitfire fly by at full speed at very low altitude. It's a sexual experience for anyone who appreciates aircraft.

I'm not sure exactly what kind of experience this reporter had with a low, fast Spitfire, but it doesn't seem to have been sexual, despite what he subsequently said.

“Subsonic cruise missiles, aircraft, fast-moving boats, unmanned aerial vehicles” — Mike Deitchman, who oversees future weapons development for the Office of Naval Research, promises Danger Room that the Navy laser cannons just over the horizon will target them all.

I'm confused. Surely the one thing a laser canon can't do is target things from over the horizon.

Having seen a couple of aircraft wrecks that have been salvaged, all they'll be able to retrieve is a hunk of junk.

Having seen pictures of World War 2 aircraft, recovered form the sea after 70 years, that looked like the only restoration needed was to hose off the mud and straighten the propeller (see image), I'd say neither of us have any real idea what condition they'll be in.

Basically, it's all about what angle the S-I stage hit the water 40 years ago. Cold deep sea is comparatively kind to aircraft alloys, although post-recovery conservation is a massive problem.

This is absolutely not about digging a basement.

The man simply likes playing with R/C earthmovers. And this is a way for him to keep on doing it during the five-month Canadian Winter, when everything is covered in snow. I doubt if he would care if it took 20 years to finish.

Sod guns, obviously the most useful application this technology would have, assuming it can have the range claimed for it, is spotting suicide vests as frisking is clearly impossible. I believe the only current option is to force the suspected bomber to undress at gunpoint, while standing well away from them.

I'll be interested to see if the Israelis start buying this technology. Though I assume it'll only take a another 7/7 in London before they put these into every tube station.

We will have solar energy as soon as the utility companies solve one technical problem -- how to run a sunbeam through a meter.
