Having been in the Air
Force, I can tell you that a "fly over"is a "salute". And since NASCAR does so much for the armed forces, I thing the military is giving that fly over "salute" as a Thank you to NASCAR fo rall their help. But it is also done right on (or about) the last note of the national anthem, therefore it's a patriotic thing to do as well.
no planes are not perpendicular to each other because for air resistance the planes are designed in a such way that air is avoided to back side and they are inclined to each other.
There are a few ways to space runners on a track. You could have a staggered start where there is one runner per lane and they each start a but higher then the next (due to which lane they are in). They could also all start on the waterfall (the curved start line).
The best way to keep track of cost savings it to start a spreadsheet. List all of your expenses on the sheet to track how much you spend each month.
There are between 40000 to 50000 planes that take off each day.
Each was taken over by 4-5 men. Two took over the cockpit and flew the planes while the others took care of the cabin crew and passengers.
2 planes. 1 each tower.
Russia and Germany had promised each other full cooperation before the start of WWII
In geometry, two planes intersect in a line. The only time this is not true is if the two planes are parallel to each other.
Yes
Yes! It doesn't matter how fast you are before you join the track team as long as you're committed and willing to make an effort. Once you start training on a regular basis you'll improve enormously. However, if you're not used to running every day you'll want to run on your own for a few weeks before the season starts, to get in shape (and also to make sure you really want to do track). Start with a mile or two each day and work up from that, but be sure to listen to your body and not try to do too much at once. Hope you have fun running track!
If there was no curve to start on not everyone would be running the same distance. The curve has different starting lines on each lane to make sure this is evened out.
Two planes, one went into each tower.
