The High Winger Printer Friendly Version
The design idea is for a medium to long range two-engine aircraft in either a larger wide body configuration or narrow body. The engines would be rear-mounted and be either similar to short distance airbus engines or those on longer distance Boeing 787 or 777 aircraft. The high wing design is based on the BAe 146/ Avro RJ and some turbo prop aircraft. The main differences are that this design could be larger or smaller and the engines are rear mounted similar to the MD 88 and others. The safety and passenger aspects of this design are listed below
Safety
As the this is a high wing design fuel tanks would be above he ground and would not be compromised in a wheels up emergency landing. The engines are also above ground level and would not be compromised in an emergency wheels-up landing. The mid wheel nacelles would be wide enough to prevent the plane from tipping over in a wheels-up emergency landing and could be equipped with inflatable air bags to act as buoyancy devices in case of a water landing. Also due to the high wing and high engine design these would not snag on waves or dig into the water if an emergency landing on water is required.
Passenger Comfort
Unlike the Avro (which is a high wing design with engines attached underneath the wings) and other traditional low wing designs, all window-seat passengers would have excellent views, and with a rear engine design noise levels would be acceptable.

Aircraft Safety Printer Friendly Version
Aircraft safety is now a big issue. Hundreds of lives can be lost at one time due to small mistakes or failures. If the plane is inevitabaly going to crash and there is no way to stop it, at present the only thing to do is to sit tight and hope you survive. My idea is as follows:
There is a device (a larger version of a pilot ejection seat) that blasts the whole passenger compartment away from the wings and engines. The rocket propellors are situated at the front and the back of the passenger compartment away from the fuel tanks and engines to prevent explosions. After say 10 seconds when the rockets have burnt out and the cabin is clear of the remains, two parachutes open up, again at the front and the back, so that it can fall horizontally to the ground. The wings and engines also have a single parachute each to keep fatalities on the ground to a minimum (maybe have a siren to warn people on the ground). The fuel/engine free passenger cabin will land safely on airbags which can be opened up manually by the pilot before contact with the land/water. They will prevent the plane from sinking or absorb the impact, which could still be quite large despite the parachutes. Admittedly, there would still probably be some loss of lives somwhere due to this but it would be far less than the plane plummeting towards the ground at hundreds of miles an hour.

Soft Curbs Printer Friendly Version
As far as I know, there is no reason why street curbs are as hard as concrete. In former days, people probably didn't have different materials, but today?
Hard curbs only ruin your car tires, and if there's a street festival and you end up sitting on the curb for a while, your behind will start aching in no time at all. So why not make street curbs from a material that's softer, yet durable and easy to clean?
