On our seventh research flight, we left Punta Arenas, Chile

2

00:00:04,200 --> 00:00:08,380

and flew to Ascension Island in the middle of the south Atlantic ocean.

3

00:00:08,380 --> 00:00:12,520

This is often the most stressful flight for the pilots,

4

00:00:12,520 --> 00:00:16,680

because there are not many places we can divert to. Thankfully, we had pretty good weather this time around

5

00:00:16,680 --> 00:00:20,800

and we made it without incident. Last time we were in Ascension, in August,

6

00:00:20,800 --> 00:00:24,850

the air quality was pretty bad. There were fires from Africa,

7

00:00:24,850 --> 00:00:28,940

influencing everything. This time around, the air quality was actually pretty good;

8

00:00:28,940 --> 00:00:33,150

we could actually see the ground on our way in. As we left Ascension,

9

00:00:33,150 --> 00:00:37,250

on our eighth research flight, heading to Lajes in the Azore Islands,

10

00:00:37,250 --> 00:00:41,250

we saw all the pollution Ascension had seen last time around, but we saw it

11

00:00:41,250 --> 00:00:45,820

as soon as we left Ascension and for nearly three hours as we were flying north.

12

00:00:45,820 --> 00:00:50,050

We saw fresh fires from Africa and the concentrations

13

00:00:50,050 --> 00:00:54,100

in that were huge. There was a mixture of emissions from the fires,

14

00:00:54,100 --> 00:00:58,250

dust from the Sahara and everything else mixed in together.

15

00:00:58,250 --> 00:01:02,250

So it made for probably the most exciting chemistry we've seen, as we flew along

16

00:01:02,250 --> 00:01:11,605

or probably the most depressing, too.
