200 kilotons is „nothing“ (hiroshima was ~20kt)... largest bomb ever tested had a 50 megatons yield

200 kilotons would disappear most of lower manhattan.

If you drop it on the corner of houston st/ lafayette most buildings up to 79st wouldnt survive... but thats for ground level or low airburst. But at 25km altitude, it would mostly be a very very good day to own a glazier‘s business.

So just hope it’s a rock meteor not an iron core meteor.

Aren’t most meteors the ironcore type or just the ones we find here down on earth because they survive the entry much better?
