world of stealth

worlds first unintentional (perhaps) radio wave absorbing fighter plane Horten Ho 229,built in 1930's by germany which had plywood outerskin making it possible to remain invisible on radars. though their range as in radius was miniscule, with maximum flying speed about 900 km/hr. there were little developement in the stealth till 50's , then with the cold war beginning to cover the world affairs , US came with magnum opus including SR-71 Blackbird,B-2 bomber which gave them liberty or a kind of fundamental right to hover above anybody's territory with being detected. these stealth planes actually satiate humans need to become invisible , espial from all detections. Try and recall the movie Mr India where the protaganist enjoys the invisibility. Latest on the repertoire (i had to look into the dictionary for its spelling) is AURORA , still not declared officially , but observes around the famous area-51 in nevada desert in US witnessing the presence of the supremo of the fighter world which can fly upto 6 Machs that is around 7500 km/hr ( that fills me with awe , a kind of amazement for the technology) , which is literally unfathomable in the sky by any present radar technology, and with that speed any existing missile can't dream to catch it.

Can continue on stealths, but need to go to the lab . These days a pretty hactic and would continue to be so for atleast another month. My working hrs are daily extending by an hour , what would happen after the assigned quota of 24 hrs would finish....
