IMHO , these speculations are hand waving , to massage the alleged properties of alleged alien craft to account for the lack of evidence
Often absence of evidence really is evidence of absence
speed
from all the information we have ufo travel at what? light speed if needed.
based on what evidence – this appears to be a made up “ fact “ created simple to underpin your claims
So if you had a ufo 500 feet in diameter going at the speed of 15,000 miles an hour come in the atmosphere. [/ quote] an can be seen at
30,400 feet, or 5 nautical miles. an the object is moving east to west.
The shuttle on re entry has a length of 37.24m [ that’s aprox 112 feet ] – and it can be see with naked eye , from the ground at far higher
altitudes , mostly because we can see the effects of its passage on the atmosphere
speed of 15,000 miles an hour the ufo would be over St. Louis in 40 second. 40 deconds later is owuld be over kansas city. in other word the
ufo travels about 400 miles in 80 seconds.
2 points , first our eyes are quite motion sensitive – we react to relative movement very well [ a hang over from our hunter gatherer origins ] ,
our brains process the images we see and assigns greater importance to objects that move than static ones
Second – an observer who is “ head on “ to the vector of the object , its relative movement to the observer is far less acute
Before you say it , these two points are not contradictory , we can perform both tasks simultaneously . as an experiment – get a friend to throw a
ball straight at you , it is easy to se because its movement is mostly perpendicular to you . Next , have him throw it across your field of vision –
again its easy to see because the movement is so pronounced , It is hard to tell what it is – but you do perceive motion --
Since we dont recognice object that small that far away we can only se 100 miles or 50 miles on each side of us (guessing it was clear
skies)
I can see aircraft at 10 ooo m plus , with ease [ in excess of the 5mn benchmark you set earlier ] – and these aircraft are far smaller than the
500f UFO of your example
the ufo would travel about 100 miles in 25 second at the speed of 15,000 mph
yes , an object at that velocity would travel that distance , but can you explain why it would not create any sonic boom , wake vortex or any other
tell tale atmospheric disturbance ?
also assuming if the ufo moved at 124 miles a second a ufo orbiting the moon would be in the area of sight an no sigh in a half second
Huh ???? it was traveling @ 4.1mps in the last sentence , what is the basis for this sudden new assumption of 124mps ?? if you are still talking about
a 500 foot diameter object – if it is in lunar it could not be seen by the naked eye under any circumstance , so why is it even being discussed
What is this e-book you are cribbing from ?? it sounds very strange and morbidly interesting
