Forget ground-based lasers. Cloud cover will defeat them completely, they are not powerful enough, and they will have no effect on re-entry vehicles which are already designed to survive a high-temperature environment. (Your speed reference is unintelligible. I think you mean to say 2.1 miles/second, or 3.43 km/sec.) Their apogee altitude will be approximately a quarter of their range distance.
LOL! I should have made a legal disclaimer that I'm not a math prodigy nor a rocketer physicist, just based my post on simple hillbilly math-a-matics using Wikipedia (1st mistake?) as the source, Mach 1 (speed of sound) = 767 mph. Mach 10 = 10x speed of sound, 10 x 767 = 7670 mph? So... yes 7670 ÷ (60 x 60) = 2.13 miles/sec. To quote Roger Clemons: "I miss-remembered" my math...That's still mind-blowing fast!?! Like Putin said, they cant stop it! Stay safe fren!! NCSWIC WWG1WGA
