Did Australian Aboriginals Plan to Reach the Continent?

Aborigines were the first out of Africa and first into Asia. Aboriginal Australians left Africa earlier that East Asians and Europeans according to analysis of DNA from a 90-year-old hair sample. Human migration from Africa first began 70,000 years ago.

Drone Lands on Athlete - Injuries

Companies are announcing delivery of parcels and takeaway food by drone. This is all advertising bling. It cannot possibly happen. Strict aviation rules will apply and this will completely rule them out. They are too dangerous. Imagine one landing on a crowd of people. Its rotors would cut flesh everywhere.

At the moment there is no restriction on their use in most countries because not many are in use. As accidents happen there will be strong calls for limitations on who can fly them. An athlete in an Australian triathlon was hit by a drone carrying a camera. She suffered lacerations to her
head. The owners of the drone said he was not hurt. In other words they denied responsibility. The first thing that must be implemented is insurance for these "flying attack vehicles". Wire protectors covering the rotors is another option. Part of a propeller was stuck in the runners head. To say she was making up her injuries is rubbish - she had three stitches.

The owner of the machine said that the drone had been hacked. This is not possible as few knew a drone with a camera was going to cover the event. Another problem is the question of licencing. The person flying the drone had a licence but the company who hired him did not. This is a gray area in the law. Oddly, the controller held a plane flying licence which does not cover drones.

CASA the official aviation authority is investigating the incident. Apparently many drones have crashed with few being reported. They are powerful machines and can quickly leave a controllers line of sight. Accurate landing software does not exist. A GPS or radar type landing system is absolutely necessary as soon as possible. Until this is done all drones should be banned from highly populated areas.

Bombs Dropped Near Barrier Reef

The Us has dumped bombs near Australia's Great Barrier Reef. It was not intentional. Two of their Marine aircraft were in fuel trouble and had to jettison the dangerous cargo for safety reasons.

Before dumping the explosive devices they were disarmed. The planes were operating from a Navy ship. The now harmless bombs are sitting in a deep channel away from the Barrier Reef. They are in the Great Barrier Reef World Heritage area, however.

Plans are under way to retrieve the bombs. Just how this is to be done is unknown at present.  It is not an international incident. The Australian government knows full well the immediacy of the action. There has been no protest. Removal will be done as soon as practicable.

An Attempt to Get Survivors to Another Planet Is Futile

Australian astronomers are searching for planets in other solar system that could sustain human life. Dr Charley Linweaver says Mankind is reaching the beginning of the end. It's time to look for a way out at least for a small group of people.  The number of planets identified orbiting other suns now exceeds 750. Though a few of these could be like the Earth, exact information is lacking.

The objective of getting people to such a distant destination is way "off the planet" at present. We do not have the technology to get people in orbit around other planets in our own solar system, let alone reaching a far away planet and landing safely.

Finding an identical planet to Earth is just not possible. This planet is a freak in regard to the universe. Most planets do not have life because they are regularly hit by asteroids and even other planets. Sending probes to  a possible twin planet would be a waste of time. It would literally take a lifetime to get a message back.
