Seems crazy to be trying to land on a napkin sized dolly when there are other much safer alternative products that can easily tow a chopper, once safely landed, into a hangar.
Is it an "ego" thing?
I recall trying to negotiate some small roof space in Miami for radio antennas where the president of the Savings & Loan skyscraper that was under construction insisted that the tiny roof would be for a helipad. Rumor was that he and another S&L buddy had a bet going as to who would be the first to land on it. Well he lost the bet because the Feds took the new bank, the just finished helipad, the helicopter the gold plated yacht, the gold plated staircases.
In the end, all he (D.P.) ever landed were some mashed potatoes serving lunch trays in prison. Probably saved his life.
