Former Navy Seal smashes wingsuit distance record in daring flight

One Navy SEAL, one mission, one wingsuit . and a world record gets
smashed at more than 140 mph.

An American veteran, retired U.S. Navy SEAL Andy Stumpf, risked his
life to support the SEAL community and set a global record in a
death-defying feat.

"Stumpf jumped from above 37,265 feet to honor friends and families
of fallen warriors to raise awareness and support for the Navy SEAL
Foundation.
The prior record was 17.83 miles absolute distance traveled in a wing suit
- this "Man on a Mission" travelled 18.257 miles, setting a new world
record.

I was wondering what kind of plane they used.
In one of the follow-ups, I see "Caravan" is mentioned.

from
https://en.wikipedia.org/wiki/Cessna_208_Caravan
"Performance
Maximum speed: 213 mph (343 km/h; 185 kn) true air speed
Cruise speed: 213 mph (185 kn; 343 km/h) true air speed
Stall speed: 70 mph (61 kn; 113 km/h) calibrated air speed
Never exceed speed: 201 mph (175 kn; 323 km/h) indicated air speed
Range: 1,240 mi (1,078 nmi; 1,996 km) with max fuel and reserves
Service ceiling: 25,000 ft (7,620 m)
Rate of climb: 1,275 ft/min (6.48 m/s)
Wing loading: 31.49 lb/sq ft (153.7 kg/m2)"

So, the plane's 25,000 ceiling was souped up to 37,000?
Did they have, in effect, an air-lock? Or de-pressurize the whole plane?

Service ceiling refers to the max height where an airplane can maintain
a specified rate of climb at max gross weight, but it's not a limit. If
you are patient, and especially if you are flying light, you may be able
to climb considerably higher.

Neither. I'm 95% sure that the Caravan is an unpressurized airplane, so
everyone would need to use oxygen at high altitudes. But there would be
no concern about pressurization or anything like an airlock.

Thank you. I had no idea they could get THAT much
higher without alterations,

Here are two crazy flyers.

With a light load and careful piloting the posted ceiling of most
aircraft can be exceeded.
And they would be on oxygen from 12-15000 ft

Thank you.
Here is a youtube about earlier record.
Presents some interesting information, esp. about
a extra hour needed to avoid "the bends".

comments include:
"Prior to take off, the crew of the C-17 and I will..."
"...have to pre-breathe (enriched oxygen to purge nitrogen
from the blood stream) for about one hour."

- this "Man on a Mission" travelled 18.257 miles

About the same distance as from the southwest tip of Staten Island to
Central Park
