You know FiFi, the only flightworthy B-29 Superfortress in the world. Well, with a little bit of luck, Doc will be airborne this year. And today was Doc’s rollout after a stunning 300,000 man-hours of restorations. Doc still has a ways to go before she’s flightworthy, but the progress has been terrific.

Which, wow, that’s a fair bit of cordage involved.

CHARLESTOWN, Mass. (Oct. 29, 2014) Boatswain’s Mate 3rd Class Pablo Solano climbs to the top of USS Constitution’s foremast during the crew’s final climbing evolution prior to Constitution being de-rigged in preparation for her entry into dry dock 1 in Charlestown Navy Yard scheduled for spring 2015.
I always get a tad queasy and dizzy watching stuff like this. Do note that our cameraman climbs the foremast, and the foretopmast, up to the crosstrees, but doesn’t climb the next segment, up the foretopgallant. Which, when making sail in the old days, not only would our sailor climb that, he’d be accompanied by quite a few others. And no safety harnesses back then. And while the weather this day in Charlestown was just about perfect, many a time sailors laid aloft in less than pleasant conditions. At night.
Yo ho, no wonder a bottle of rum was needed for the sailor’s life!
As the situation in Ukraine continues to deteriorate, with the Russian military and its “rebel” minions never having honored the Minsk-brokered “ceasefire” for even an hour, something like low-grade panic is setting in among NATO capitals. Western elites have a tough time sizing up Putin and his agenda realistically, for reasons I’ve elaborated, and the situation seems not to be improving.
German has a delightfully cynical line, die Hoffnung stirbt zuletzt (hope dies last), that sums up much of the wishful thinking that currently holds sway in Berlin, Paris, and Washington, DC. As the reality that Putin knows he is at war against Ukraine, and may seek a wider war against NATO too, is a prospect so terrifying that thousands of Western diplomats and “foreign policy experts” would rather not ponder it, so they don’t.
A classic example comes in a recent press report about how Western foreign ministries are striving to prevent Putin from doing more to destabilize Eastern Europe. Amidst much dithering about how to deter Putin — more sanctions? maybe some, but not too many, weapons for Ukraine? how about some really biting hashtags? — NATO leaders aren’t coming up with anything that can be termed a coherent policy, much less a strategy.
Western nations have consistently underestimated Putin’s willingness to use force.
How can we forget Putin overseeing the Second Chechen War? The 2008 invasion of Georgia? We’ve already effectively conceded Crimea. For that matter, who seriously thinks diplomacy will ever return eastern Ukrainian lands from Moscow’s grip?
Will we see a straight up invasion of Germany right out of Red Storm Rising? Probably not.
But almost certainly some “incident” will eventually take place in Latvia or one of the other Baltic nations that will, by amazing coincidence, be used by Putin to justify some Russian intervention.
Increasingly frequent snap military drills being carried out by Russia near its eastern European neighbours could be part of a strategy that will open the door for a Russian offensive on the Baltic states according to defence expert Martin Hurt, deputy director at Estonia’s International Centre for Defence and Security.
The Lithuanian and Estonian defence ministries have expressed alarm at the increased military activity, and drawn comparisons with moves prior to the Russian invasion of Crimea.
Commenting on Russia’s announcement last week that its armed forces will not cease holding snap military exercises, Hurt, who has previously worked for Estonia’s Ministry of Defence as well as for the armed forces of both Estonia and Sweden, warned against taking this news lightly.

I’ll leave it to URR to write the history of one of the most vicious battles of the war, a battle that still serves as a touchstone to the Marines today. He has several weeks to address it. That tiny island you see in the photo below would take six weeks to secure.
Uncommon valor was a common virtue- Nimitz
For those that are interested in this sort of thing. Personally, I think the differences with an Army Infantry Regiment are minor, but intriguing.
We think it goes without saying that military aviation is fraught with hazards. Actually, it is a great deal safer today than in days past. But even so, it is still quite hazardous. It is not at all unusual for 10 percent, or even 25 percent of a given fleet of tactical aircraft produced to be lost to maintenance, operational, or combat losses over the course of a type’s service life. For instance, Canada lost 110 of the 235 CF-104s it operated in 25 years of service, or 46%.
Right up to the end of World War II, when an aircraft was in distress, the crew left by bailing out, that is, simply stepping out of the cockpit or fuselage. But the speeds of aircraft by the end of the war, and the speeds of jets soon after the war, increasingly made that a very hazardous proposition. A pilot bailing out was quite likely to strike the empennage with fatal results.
And so, the ejection seat was born.
Early ejection seats were mostly of the “gun” type. A cartridge much like a huge blank shotgun shell was fired into a closed, telescoping tube attached to the pilot’s seat. The shell filled the tube with expanding gasses, causing the tube to extend, and forcing the seat up the rails it was mounted on. Also called a catapult, this gun mechanism was sufficient to force the seat and pilot high enough to clear the vertical stabilizer of the stricken craft.
The gun type seat wasn’t without its drawbacks. First, it imposed very high g-loads on the pilot. Spinal injuries were to be expected. Second, getting the seat over the tail was about all the early ejection seat accomplished. The pilot still had to separate himself from the seat and manually pull a ripcord to deploy his parachute. This complication actually raised the minimum safe bailout altitude, as it took time, time in which the pilot would be falling to earth.
While a great deal of development of ejection seats early on focused on safely egressing at supersonic speeds and high altitudes, it turned out that most emergencies tended to happen at lower speeds and altitudes. What was really wanted was a seat that could safely allow a crewmember to escape at very low altitude. Simply using a larger gun charge wouldn’t work. That would merely exacerbate injuries to the crewmember’s back.
And so, the British firm, Martin-Baker opted to use a rocket motor. The catapult was still there, to give the seat its initial impetus. But a rocket motor would then loft the seat to a higher level. As an added bonus, the combination of the gun and rocket gave a greater total vertical vector, but a imposed a lower g-load on the pilot.
Other advances included automatic separation of the pilot from the seat, and automatic deployment of the parachute.
As time has passed, ejection seat designers have added improvements to seats to continuously expand the envelope of where and how a crew can successfully eject. First, there are “zero/zero” seats, where a pilot can be at zero airspeed and zero altitude and successfully eject.
Other improvements include not just automatic deployment of the parachute, but ballistic deployment, where pyrotechnics are used to speed up the deployment of a parachute.
At one time, the US Navy was working on a vertical seeking ejection seat that would allow ejections inverted from very low altitudes.
A modern ejection seat in a high performance fighter such as the F-35 is quite sophisticated.
Speaking of sophisicated, Martin-Baker isn’t the only manufacturer of ejection seats, but they do have one of the best PR departments in the business. If you use a Martin-Baker seat, you are eligible for induction into their Tie Club.
The primary objective of the Club is to provide a distinctive tie to be worn with civilian clothing which therefore provides a visible sign of the members’ common bond. Every Club member is given a certificate, membership card, patch, tie, pin or a brooch for the women. All the Tie Club memorabilia depicts a red triangle warning sign which is the recognised international danger symbol for an ejection seat.
Every good company knows that your best salesmen are your customers.
The Russians, by the way, are no slouches in the bang seat business. Their excellent K36 series seat was forced to put on a convincing display at the Paris Air Show a time or two.
I didn’t emphasize enough how you should definitely read this piece in The Atlantic about the Islamic State.
And when you’re done with that, you might want to read this piece from the Council on Foreign Relations.
I’ve mostly skimmed the second piece. Haven’t quite digested it yet. What are your thoughts?
