Weather Balloon script crash

[dpculp]

When executing the script weather-balloon.xml as supplied by the repo I get a core dump "Floating point exception" after about 4980 seconds of virtual time. This is at the point in the flight around 92K feet where the balloon is deflating and beginning descent.

I changed the termination event to stop execution at 80K feet of altitude and the script ran perfectly.

It seems the transition from ascent to descent is not working presently in the weather balloon (gas cell) model. I'll investigate further.

Some further details on the balloon burst, and code formatting practice for me :) I added a notification of the burst event.

Confirmed ! The script scripts/weather-balloon.xml crashes at 92 kft although the simulated time at which this occurs on my test is lower than yours (4260s vs 4980s):

I have created the issue #654 to log the issue as a bug.
