Patience
and Practice
We all have seen some of the results - helicopters landing on
shipboard and on water - others landing in a yard, backing and
going straight up. The sketch of da Vinci's vitalized by Sikorsky and

be a long time before helicopters will be in our back yards,
because experience has taught us that much development work is yet
ahead - development that must take place after you and I become actual
customers. ●
