What could happen to a building like one world trade center if an airbus 380 hits it at full speed ?

Older planes are usually very good purchases, IF they have been well maintained over the years. Airplanes have to be inspected annually by an A&P mechanic with an Inspection Authorization so they are usually very well maintained. Any purchase should include having an A&P mechanic review the airframe and engine logs and evaluation of the plane, including looking at how many hours the engine has since overhaul and checking compression. I had a 1966 Cherokee 140 for several years and finally sold it when I bought my current Experimental aircraft (a BD-4). It helps a LOT if you can get an A&P license and maintain you own plane though.

Birds can't read the FAA regs.

To an atheist, the threat of hell is just one more brainwashing trick of religious education. There comes a time, if one is alert through life when one finally discovers that it's purely ridiculous to pray to God for your team to win or for this to happen or that to not happen. There's no value in it. The only good it does is to give the person praying false hope. Face it, stuff happens. Unexplainable things happen and religious people call them miracles. Religion was invented because people couldn't understand why things happened so they created a deity as an easy explanation. If you research religion, the Jesus-like character has existed in many different stories in many different times even to ancient times (many many years BC) The Bible is so often taken out of context and only the portions that are convenient to the follower are ever followed. Many current trends, such as tattoos are expressly forbidden in the Bible,. In today's world a majority of Christians seem to be conservative politically which does not even begin to follow the teachings of Christ, who promoted social programs, give your riches to the poor, etc.... No atheists need not fear hell because it will be filled with Christians. While Christians all endure the rapture the atheists will gladly stay behind and take care of the Christians' pets.

Great book to read is "Wings On My Sleeve" by Eric Brown. Only pilot in the world to have flown most of the airplanes of WWII.

I recently browsed a forum where this was debated by the FE believers vs normal OE people. (Obloid Earth).
The FE'ers simply believe that photos, videos etc are hoaxes. :))

Usually, once you have a private pilot certificate you would go for an instructor rating and work as a flight instructor to build flight time (while making money). Along the way you could also be working on your commercial, multi engine, and air transport pilot ratings and certificates. It takes time to get into the airlines, mostly because you need to build flight time and experience. Even when you first break into the airlines the pay is kind of pathetic, but it builds quickly over time.

How much fuel would that be in pounds? Remember that the plane will need to get into the air, if it is too heavy it wont be able to takeoff. Also what if something happens that requires the plane to come back and land?

Gliders (soaring aircraft) are designed to produce high lift at minimal airspeeds, with minimal drag. That is, for all airplanes there is a lift/drag curve that dictates the speed that produces the maximum lift for the minimum drag. Sailplanes have only the thrust given them by gravity, to produce the most wing lift. Add to that whatever updraft they can find, and that's what's keeping them aloft.

To achieve this, they typically have long wings with a lot of what is called "wetted area" - the area affected by the airflow. Consider also that a major component of drag is a function of the velocity, and you discover that, just like in a car, it takes a LOT more power (thrust) to go 100 mph than 50 mph.

The LSA speed limit is a legal one. I am not aware of any country that imposes a speed limit on sailplanes (other than that pertaining to the airspace that they are in). But generally sailplanes are not going to give you high performance speeds. And what does give you speed limits on sailplanes is going to be Vne (the never exceed speed), determined by the structural strength of the wings. I think you will find that the indicated airspeed (IAS) for most sailplanes is relatively low.

Michele,
Airbus 321 can't fly between LHR to JFK. Aircraft range is 5950km and the air distance between LHR and JFK is 8,112 km..
with regards.
