Australian company SkyLifter has designed a heavy-lifting, vertical ascent and descent aircraft that will operate as a practical flying crane. The aircraft is designed to take off where helicopters leave off, with vertical pickup and delivery capability of over-size, fragile or bulky items up to 150 tons, and potentially more. The long flight duration of 24 hours ensures a good distance range and adds flexibility to logistics. The aircraft can loiter over a ground location for long periods using minimal energy.
