These VVER 1000 reactors are housed in a confinement shell capable of being hit by an aircraft weighing 20 tonnes and suffering no expected damage.

They could traverse 360 and launch an aircraft weighing at a speed of , although no suitable aircraft was in service until the Beriev Be-2 seaplane entered service in September 1939 .

And such aircraft, weighing only ounces, are more susceptible to wind gusts, updrafts and the pounding of rain.

The rate of sink once the engine had stopped, from an aircraft weighing six tonnes plus five hundred gallons of fuel, plus another three hundred handing under the wings, is fast.

Regardless, the HondaJet, which has been under development for nine years, will face growing competition in the market for "very light jets" - aircraft weighing a maximum of 10,000 pounds that can be flown by one pilot.

The bridge has a single 191' (58.2m) span, is 217' (66.1m) wide and is designed to carry a 747-400 aircraft weighing 894,900 pounds.

In addition, it amended the definition of 56-passenger jets that could fly to other states to include any aircraft weighing less than 300,000 pounds which has been reconfigured to accommodate 56 or fewer passengers.

The first rule will require F.B.I. background checks on pilots flying any aircraft weighing more than 12,500 pounds, which would cover most smaller, privately chartered planes and corporate jets.

The second will require any aircraft weighing more than 100,000 pounds - generally any plane with more than 60 seats - to have the same security screening for passengers that commercial aircraft do.

The tail strike occurred because the rotation speed had been mistakenly calculated for an aircraft weighing 100 tonnes less than the actual weight of the aircraft.
