00:00.300 --> 00:01.133
^- Hey there, everyone.

00:01.133 --> 00:03.410
^I'm Staff Sergeant Javon Smith, here with your look

00:03.410 --> 00:04.460
^around the Air Force.

00:05.320 --> 00:07.630
^The National Aeronautics and Space Administration,

00:07.630 --> 00:10.410
^along with the German Aerospace Center, or DRL,

00:10.440 --> 00:13.350
^conducted biofuel testing throughout Europe last week.

00:13.670 --> 00:16.360
^A DC-8 jetliner was accompanied by the DRL's

00:16.360 --> 00:19.830
^Advanced Technology Research Aircraft, Airbus A320

00:19.910 --> 00:21.860
^to study the effects of fuel composition

00:21.860 --> 00:23.450
^on contrail formations.

00:23.700 --> 00:26.060
^Standard jet fuel has multiple contaminants,

00:26.060 --> 00:28.860
^while the biofuels being tested are simpler compounds

00:28.860 --> 00:30.060
^and burn much cleaner.

00:30.300 --> 00:31.880
^There's a general push to reduce

00:31.880 --> 00:34.270
^the environmental impact of the energy sector,

00:34.290 --> 00:37.050
^both in ground based and airborne transportation.

00:37.460 --> 00:40.100
^Scientists say contrails generated by aircraft

00:40.100 --> 00:41.540
^are a concern to the environment

00:41.540 --> 00:43.440
^because they trap heat, and make the surface

00:43.440 --> 00:45.000
^of the Earth warmer at night.

00:45.390 --> 00:47.480
^This is the first time the DRL and the

00:47.480 --> 00:49.730
^United States Air Force have worked together.

00:50.450 --> 00:53.410
^The Air Force began the roll out of Tier 2 Physical Training

00:53.410 --> 00:55.530
^Standards at Andrews Air Force Base, Maryland,

00:55.530 --> 00:56.620
^earlier this month.

00:57.020 --> 00:59.380
^Tier 2 Standards will exempt battlefield airmen from

00:59.380 --> 01:01.900
^three of the four components of the Air Force fitness

01:01.900 --> 01:04.820
^assessment, because their occupational fitness assessments

01:04.820 --> 01:07.340
^already effectively measure the fitness required

01:07.340 --> 01:08.340
^for their missions.

01:08.540 --> 01:09.880
^Air Liaison Officers and

01:09.880 --> 01:11.760
^Tactical Air Control Party Operators

01:11.760 --> 01:14.850
^will soon see implementation of the new PFT requirements,

01:14.890 --> 01:17.330
^making them the first career fields in the Air Force

01:17.330 --> 01:20.570
^to have job specific and operationally relevant standards,

01:20.570 --> 01:22.530
^as well as a second fitness assessment.

01:22.900 --> 01:25.360

01:25.360 --> 01:27.750
