<p>A platform (1) for the aerial delivery of payloads into aquatic environments has a staged v cross-section formed by two walls extending from an end part. The portions (6) of the two walls adjacent to the end part diverge from it at an angle and, together with the end part, form the tip of the platform. The remaining portions (7) of the two walls, remote from the end part, form the body of the platform, and diverge at an angle that is greater than the angle. When the platform is deployed onto the surface of a fluid, it initially experiences a period of low deceleration as the tip penetrates the surface, followed by a period of higher deceleration, as the body contacts the surface.</p> |
