Failure Of The First Trident D5 submarine-based test launch

In 1971, the US Navy issued a requirement for a submarine-launched, multiple warhead, ballistic missile with intercontinental range and a stellar-inertial navigation system. This would give the Navy capability against Soviet missile siloes and other hardened targets. Lockheed proposed a two-phase program. Trident C-4 would fit in launch tubes in existing submarines, with a range 50% greater than Poseidon. Trident II D-5 would have longer stages, requiring a new class of submarine to be built to accommodate it, but have the desired intercontinental range. Lockheed began development of the Trident II in October 1983. First launch was in January 1987, and first submerged launch in March 1989. This was a failure, revealing problems with the first-stage engine nozzle.

There are two great mysteries that overshadow all other mysteries in science. One is the origin of the universe. That’s my day job. However, there is also the other great mystery of inner space. And that is what sits on your shoulders, which believe it or not, is the most complex object in the known universe. But the brain only uses 20 watts of power. It would require a nuclear power plant to energise a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that’s a compliment.

I need feminism because most men’s restrooms still aren’t equipped with baby changing stations. As someone who was married to a man who had sole custody of his young son, I’m hyperaware that feminism means EQUALITY, not female superiority. Feminism should and does support a man’s right to be as much of a parent to his child(ren) as any mother is allowed/expected to be.

This is a constant problem for Mr. Tea and myself. We’ve got twins, so even though I can change one kid on the change table in the ladies’ room, he’s left standing sort of awkwardly in the lobby with a messy child while I change one, come back, and get the other.

Nobody’s suggesting that men aren’t parents, so the lack of change tables goes well beyond ‘gender role reinforcing’ and straight into ‘ridiculous’.

My dad actually almost got kicked out of a mall once for changing my brother in the womens room of a mall. The only reason they didn’t call the cops on him was because the ladies in the room supported him.

I’d never even considered this but I support it

I have seriously always wondered about this. I mean, most malls and such here have “family” rest rooms with change tables but I mean I have watched many a father bring his child out to the car to change because they don’t have rest room access. I am SO glad this is a post!!
