Fastest Missile ever!
« on: February 16, 2008, 08:33:00 PM »
Assuming the Freighter is still 80 miles off shore.
80 miles is most likely 80 Nautical miles just over 2000 yards per mile
80*2,000=160,000 yards=480,000 feet
480,000 / 28 seconds = 17,142 feet per second = 11,689 Miles per hour

Thats MACH 15.36 ----Can't happen

But if it was an actual 80 miles out...not nautical miles...it would only be 154mph...is that correct?

A normal mile is 5,280 feet.

80*5,280 = 422,400 feet / 28 seconds = 15085.7 feet per second =10,286.5 Mph = MACH 13.51

Still too fast

What did regina spout off about the distance to landing?  I don't think it started with 80 did it?

I think the boat is only 8 miles off shore now. That would put the missile in the MACH 1.5 range which is easily doable.

But that should be close enough for the islanders to see it on the horizon, if there wasn't a bubble that scatters the light differant.

Hmmm, I'm wondering if after the rocket makes it to the apex, it could increase speed with he rocket still firing, but now going down....I never had calculus or trig...whichever may apply...

I used this conversion chart
still came up with 154.8mph

I'm pretty sure with speeds like that the rocket would have burned up from the friction, not to mention be destroyed by the impact and causing a large crater.

Anyone else wonder why they decided to launch a supersonic missile to land 20 meters away from to only functioning way off the island. Seems really stupid.

here is another conversion calculator....I think your math is off....still 157.8mph

go get in your car, drive 75 mph and see how long it takes you to go about 75 miles.

then half that....and that is how long it would take you to go 75 miles (roughly 80 nautical) at 158 or whatever mph.

You are using the 31 minutes, I am using the 28 second time of flight in real time that the boat said it landed.

thats true...it could make more sense if the boat was closer...we just dont know...but logic would dictate if they made contact, the freighter would move closer to the estimated area of the island....

The apollo moonshots had saturn rockets and had to reach an escape velocity of over 25000 miles per hour.  Sound travels 742 mph at sea level, so 25000 divided by 742 equals (anybody have a calculator).  My guess would be mach 33.

Most ICBM's travel at over 15000 mph and interceptor missiles travel even faster.  But, here, ballistics mean nothing anyway (there is another unknown variable).  We know that the rocket couldn't have been going too fast cause if it was, the kinetic energy from hitting the ground would (even with a small rocket) would have blown up the entire area.

If you want to see what happens when a rocket or jet hits something solid, watch the you tube video of a F-4 Phantom hitting a cement bunker (type in F-4 Phantom and bunker). 

The airplane literally evaporates.

But still I think it is possible either way....anyway it works ot its a moot point, me thinks lol
