Thank you.
However, in the opinion of many, freight carriage by means of airships could be too costly, somewhat too slow and therefore a bit less profitable.
You say that Transport Canada does not want to deal with this file, which is rather strange. Since airships have been in existence for 100 years and have never been very popular, I wonder how come they are being presented today, in 2012, as a miraculous solution. If they are so miraculous, why did they not raise any interest earlier?
