1 Today alcohol is involved in 37% of all traffic deaths among persons aged 16 to 20.

The corresponding cost and price benefit, which SpaceX President Gwynne Shotwell has said could give customers around a 30 percent discount over expendable versions, is not yet listed in the price chart. Prices are shown as $62 million for the Falcon 9 Full Thrust and $90 million for the Falcon Heavy.
Musk, the billionaire founder and lead designer of SpaceX, who first announced plans for a heavy-lift rocket in 2011 and constructed the Falcon Heavy by strapping together three boosters from the companyâs smaller but proven Falcon 9 cargo rockets, had downplayed expectations of a successful launch. On Monday, he had estimated Falconâs chances at about 50-50, and said he feared a launchpad-destroying explosion similar to the Falcon 9 fireball that created extensive damage in September 2016.
