**Reiny**, Monday, February 11, 2013 at 10:36pmFor height at lower angle:

tan 15°10' = height1/140

height1 = 140tan15°10'

in the same way:

height2 = 140tan29°30'

rise of the balloon in that change of angle

= 140tan29°30' - 140tan15°10'

= 41.256

I am sure your units are not correct.

How can they even see the balloon from 140 km away ?
