NEW YORK — Boarding an airplane has never been safer.
The past 10 years have been the best in the country's aviation history with
153 fatalities. That's two deaths for every 100 million passengers on
commercial flights, according to an Associated Press analysis of government
accident data.
The improvement is remarkable. Just a decade earlier, at the time the safest

As a commercial pilot here is my theory:
Preface: Please note that the Displaced Threshold for 28L has recently been
moved, I.e. the runway has recently been shortened since its last paving.
This is evidenced by the "blacked out" old Threshold markings on the current
runway surface along with the newly painted markings. You can vision the
old markings and the original Threshold markings if you Google Map it. The

If the plane bounce up after contacting the runway, you were having
excessive airspeed, which means you didn't pull back early enough.
You need to constantly adjust the back pressure during the entire flaring
process. Look outside to judge where the runway is, and look inside to
maintain airspeed. When you enter ground effect, gradually pull back to slow

首先，德国人的首要目标是什么？希特勒的想法是很明确的，那就是消灭红军主力，而
不是攻克莫斯科 (D. Glantz, The Battle for Leningrad, Kansas Univ. Press, pp.

What makes an aircraft fly is the relative speed to the air, not the ground.
your device can run at 10,000 km/hour and it wouldn't make one bit of
difference as to how fast the aircraft have to be before it hits the runway.
On the other hand, if you can get a giant fan to blow air at 300km/hour,
then the aircraft can indeed have 0 speed relative to the runway. |

发帖数: 29846 | 46 WASHINGTON -- Four years ago, when then-Sen. Barack Obama was campaigning
for president, he said of Afghanistan: This is "a war that we have to win."
He also claimed, "The Afghan people must know that our commitment to their
future is enduring because the security of Afghanistan and the United States
is shared." But after three years of Obama's being commander in chief, it
ought to be clear that he never really believed his own campaign rhetoric.
Now, in the aftermath of recent setbacks, his wor... 阅读全帖 |

"They came in very quickly. A lot sooner than a lot of people expected. They
were on right at it, and they were able to get Governor Mike Pence and
everybody else off that plane quickly and safely," said one LaGuardia worker.
"I think Governor Pence's comment about the relief in seeing red flashing
lights on Port Authority police vehicles within 10 seconds speaks for itself
," said Port Authority Executive Director Patrick Foye.

launched within three hours of President Donald Trump making the final
strike decision, defense and White House officials said Friday.

1. Support undo and redo on a picture.
-- Two stacks, one for each
2. Now each command has a cost and we need peekMax() to get the most
expensive command so that we can potentially save the snapshop (of pic) and
store it to server for that command. How do you support the peekMax() method?

发帖数: 1059 | 50 我来认真地分析几句。总之应该是个不错的公司，但是是不是适合你要自己定。
1. 产品, 用户和增长潜力
Snapchat已经从private messaging开始发展为以照片，音乐，视频共享为
主的social media平台。日活用户100M以上，月活据估计在200M左右。是增长最快
的社交网络。
主要用户是14-25岁的年轻人，也就是90后们。他们很容易接受网络，已经有相当强
的购买能力。而且会更强。
增长前景应该不错，但能否达到像Facebook那样1B以上的日活用户则关键在于怎么
吸引35岁以上的用户。
2. 盈利能力
主要的盈利渠道还是广告。目前还在发展一些其它的付费服务，比如说交$.99就可以
把已经expire的消息救回来。应该说除了广告，还是有很多其它m10n机会的，毕竟
是个入口级的产品，想想wechat就知道。
从leak出来的数据看。2014年10月开始做广告，到年底3个月收入3.1M。拓展到全年
是12M左右。2015年号称收入50M, 2016的目标是收入200-300M. 典型的互联网公
司收入快速增长的曲线。即使不算特别快的，也很厉害了。只要能做到，应该说... 阅读全帖 |
