As soon as the plane hit the water, “a small flotilla of boats” arrived to rescue passengers, including the Coast Guard Cutter Ridley, and New York Police Department divers. Tom Fox, general manager, brought the New York Water Taxi to assist as well.

Mayor Bloomberg said the pilot did “a masterful job.” I agree–landing a plane dead stick over America’s densest metropolis without a single casualty is amazing. If the City of New York doesn’t award him a stipend and medal, US Airways had better write him a $1M bonus for his excellent performance. The Airforce might also be interested in someone of his talents.

As news spread across the world of Iran’s provocative missile tests, so did an image of four missiles heading skyward in unison. Unfortunately, it appeared to contain one too many missiles, a point that had not emerged before the photo was used on the front pages of The Los Angeles Times, The Financial Times, The Chicago Tribune and several other newspapers as well as on BBC News, MSNBC, Yahoo! News, NYTimes.com and many other major news Web sites.

This is the image that ran in the papers and has recently been retracted for being “apparently digitally altered” by Iranian state media. Agence France-Presse said the fourth missile “has apparently been added in digital retouch to cover a grounded missile that may have failed during the test.” Here I’ve blown up a portion of the smoke so you can clearly see the ’shop:

A plane is standing on a runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in the opposite direction). Can the plane take off?

There are a number of forces here that apply: gravity, the force of the engines / airspeed / lift, and the drag of the wheels against the conveyor / the speed of conveyor. However, the wheels provide essentially a frictionless boundary between plane and ground; unlike car wheels, the wheels of an airplane spin freely in place. So, as the conveyor belt speeds up, the airplane stays in place, but its wheels spin at the same velocity. Furthermore, the lift of the airplane is relative to its airspeed, and its engines push against air. So, the airplane will accelerate forward and take off as normal.

The commenter “Max” has a nice summary as well: “A comparable example in my mind would be a car on a treadmill. If the car is being pulled along by a winch and the wheels are turning freely then the car is going to be pulled at an identical rate whether or not the treadmill is there or not (assuming as you did that the treadmill’s speed is inverse to that of the car).”

On another note, to everyone saying, “It’s obviously not a bomb, they should have known better!” : that’s really condescending. My mother doesn’t know what a breadboard is. My neighbors don’t. Several of my friends don’t. I’d wager the great majority of the US doesn’t know, for better or worse. Don’t pretend that everyone else knows what you know, especially when you are judging circumstances after being given all the facts at once in hindsight.

See the problem is that security personnel, if expected to guard against bombs and bombers, should be able to positively recognize bombs. Your mother and neighbors are not airport security officers, military police, or Boston police for exactly that reason; they don’t know what bombs look like.

Then there are comments #7 and #8, which feel like the police brutality (they arrested her outside the airport with force) is justified:

Wow, she sure put the “mor[on]” in sophomore! Maybe for her next art project she can run around the airport screaming “I’m Al Qaida! Look at me! I’m Al Qaida!”

I’d have wished the above moron had written “more[on] in sophomore;” it would have bee more funny. That said, there’s nothing wrong with a geeky girl wearing a hoodie with some blinking LEDs. As far as I know (and I think the statistics support me here) no one has ever died or been injured, directly or indirectly, by an LED. And, I fully support her right to voice her political opinions, even in the airport. Unfortunate the climate these days means wearing we will not be silent arabic / english t-shirts will probably get you detained.

I thought MIT students were supposed to be a bit more intelligent than the rest of us. Walking into an airport with an electronic device strapped to her chest ….. a very stupid action. She is lucky to just be in a cell, but I have a feeling a lot of people (including her) will never understand why, this time, the Boston Police are in the right.

This one is begging for me point out that 99.99998% of people walk around airports with iPods tucked around their chest or body somewhere… and I’m not even going to start counting people with pacemakers, who actually have an electronic device embedded in their chests! An electronic device isn’t a bomb, and if you think airport security can prevent terrorism, you’re wrong.

Finally, on a lighter note, Rob Cockerham’s comment #27 takes the cake, and eats it too:

I can’t believe NBC is promoting Bionic Woman like this. What a terrible idea.

I always thought when I bought plane tickets from Expedia that somewhere tickets, real tickets, would be issued to me, a seat reserved and noted, etc. Unfortunately, everything seems to operate in batch-mode, where airlines give blocks of seats to online vendors who match them together in strange ways that allow the possibility that the tickets they’ve resold may not represent spots on a plane:

I’m not the only one complaining about this practice. See:

• Expedia dot SCAM?
• Rate IT All Expedia
• Mouth Shut on Expedia
• Victims of Expedia

My bank account also looks quite cute, waiting for $3000 in refunds:

This isn’t to blame Expedia though. To their benefit, they are refunding the total amount over those two cancelled flights. Also, their customer service reps on the phone were extremely apologetic and kind. It’s more a flaw in the system of batch-time ticket booking. With a real-time synchronized process, this sort of thing could not happen.
