Silver Boy - all the details of the money raised and accounts are in the investors section on the silverjet website. The think that is killing the airline is the cost of fuel which must be around twice of what was expected when they did the buisness plan. You can lookup the cost of jet fuel at
www.ft.com and is around $900/tonne. That may require $25k-$35 to cross the pond just in fuel costs.
The airline is totaly dependant on a large drop in fuel cost for it to it keep going.
Being broke is normal for an airline. An established airline can operate for decades while broke as long as it does not need to expand. To expand you need more cash which is when the books become vital.
