How likely is it for a childs balloon to travel 3,000 miles?
Storey in Mail Online
In the comments someone supposes that this is unlikely due to the balloon would only last a short time and the prevailing winds would not bring it to Laos. Seems logical. But then 3,000 miles divided by say average 25 miles an hour the balloon would only need to travel for 5 days.
What say the dope?
