The Mil V-12 was the largest helicopter ever built (37-meter long!). It performed its first flight in 1968, and outperformed all the other helicopters in the world. Thanks to its twin rotor, it could lift up to 44 tons as early as 1969. It never entered service as this prodigious prototype remained at the project stage, and for uncleared reasons, its production was cancelled.
The U.S. F-35Cs – 5th-generation-fighter a/c – showed below are CATOBAR fighter jets. CATOBAR stands for Catapult Assisted Take Off But Arrested Recovery. It means that this variant of the F-35 JSF – Joint Strike Fighter aka Lightning II – is designed to be launched from a CV (Carrier Vessel aka aircraft carrier), and it is designed to land thanks to arrestor (or arresting) wires and hooks – Video:
The V750 is a brand new unmanned helicopter designed by Qingdao Haili. It successfully completed its maiden flight in Shandong province three weeks ago.
This UAV has a load capacity of more than 77 kg. It can reach more than 160 km/h, and it can be remote-controlled from up to 153 kilometers away. The V750 drone could be used for ISR purpose. With a weight of 100 kg, it is deemed to be the largest drone in China as it could be as large as the American MQ-8 “Fire Scout”.
According to a Wall Street Journal report, the American carriers have made a lot of money thanks to add-fees – $22 billion in 2010.
For instance, Matt McCall, the president of Penn Financial Group reports in the following video that he had to “pay 50 dollars for 4 inches” exceeding the standard luggage size the night before.
Most people pay such add-fees as they do not want to change bags in the very last minutes. It depends on the airlines – as in the video – but the fee for overweight carry-on bags can be twice as expensive. Some passengers are willing to pay add-on fees if needed.
However some other passengers may not have time to perform the luggage change required, and they pay add-on fees just before departure. So they pay, and the airlines rake the add-on fees revenue which is to increase even further:
Andre Borschberg took off from Switzerland, flew across France,then Luxembourg, and Belgium, and finally landed safely thanks to the sunlight-powered HB-SIA Solar Impulse in Brussels in the evening of May 13, 2011. Bertrand Piccard was there:
