One of the comments suggests that applying rudder so jumpers find it easier to get clear is standard. If the rudder was left, and the door is on the left, it makes sense.
Beating the skydivers to the ground is pretty awesome as well. Here is a Do-28 doing roughly the same:

We actually had an incident recently with a large tactical jet operator in central Florida. They were using IFR commercial jet traffic as targets for practice intercepts, doing really extreme maneuvering (5000ft-17000ft climbs and dives, and lots of unpredictable turns) in the middle of a published STAR (Standard Terminal Arrival Route,) and causing all manner of havoc. Nothing outwardly dangerous, but extremely difficult to deal with, since they weren't talking to us. We've since established a letter of agreement with them that designates some airspace for their operations, and obligates them to talk to us for certain operations.

This is a few pages back, but do you mean Draken International? It's fun going on Google Earth and seeing MiG-21s sitting behind a hanger at the regional airport.

Of course Florida would be the state to have a PMC air force.

I can neither confirm nor deny.

I will say that their display at Sun 'N Fun (which is at their home airfield,) was underwhelming. They had a Magister and an A-4 static display, IIRC, and nothing else. :v:

It's in Lakeland, where Legoland (the former Cypress Gardens) is. About an hour northeast of St. Pete, which in Russian terms is just down the block.

They're a legit PMC as far as I know. I think most of their work is aggressor training, but they offer services replacing military aircraft like tankers and recon planes. As far as I know they don't have any ordnance sitting in their hangers, so presumably they'd be supplied by whichever nation hired them for service if they actually had to go into a combat zone.

Sometimes an Airbus really is calling the pilot a retard*:

NTSB posted:

When ATC advised the aircraft would be next to depart, the first officer began reading the remainder of the taxi checklist when a flight attendant advised a passenger was in the lavatory, subsequently advising the passenger was on the way back to the seat. The checklist was completed while the captain taxied the aircraft onto runway 27L. While lining up for departure the captain recognized the wrong runway 27R had been entered into the FMC and instructed the first officer to correct the entry. The aircraft came to a full stop on runway 27L while awaiting takeoff clearance. The FMC was reprogrammed to runway 27L a few seconds prior to receiving takeoff clearance.

11 seconds after receiving takeoff clearance the thrust levers were moved into the MAX CLIMB detent and nose down inputs were provided by the captain's side stick. The thrust lever was subsequently moved into the FLEX detent, a chime sounded together with an ECAM message that thrust had not been set, the thrust levers were moved to the CL detent for a second and again into the FLEX detent, 3 seconds later the captain announced "They are set."

According to the cockpit voice recorder neither pilot called out 80 knots. Both pilots recognized at about the same time, that no V-speeds were displayed on the primary flight displays. When the aircraft accelerated through 86 knots an aural alert "RETARD" sounded. The captain queried "what did you do, you didn't load. We lost everything", while accelerating through 143 KIAS the captain stated "we'll get that straight when we get airborne" and continued takeoff. Accelerating through 152 KIAS the captain initiated rotation, the first officer stated "wh*. I'm sorry", the aircraft reached 6.9 degrees nose up at 164 KIAS and the nose weight on wheel sensors indicated airborne.

Over the next 4 seconds, with the nose wheel indicating airborne and the main wheel sensors indicating ground, the captain's side stick was pushed forward (nose down) and back (nose up) two times reaching 16 degrees nose up and 16 degrees nose down maximum inputs, the aircraft's pitch and vertical acceleration followed the pitch inputs. In response to the next nose down input, as vertical acceleration reduced, the thrust levers were reduced and the side stick was again pulled (nose up input). The vertical acceleration decreased, the thrust levers were reduced to idle, 4 seconds after the nose gear indicated airborne the weight on wheel sensor changed to ground again, the pitch reduced to -0.4 degrees, and the vertical acceleration suddenly increased to +3.7G consistent with the gear impacting the runway surface, at the same time the captain's pitch input again reached the maximum of 16 degrees nose up. The side stick input cycled nose down and nose up inputs over 2 seconds again and reached 16 degrees nose up again, nose and main gear sensors indicated airborne and the radio altimeter reached 15 feet AGL, the side stick input went to a nose down input, and the aircraft descended, the stick input changed to nose up again and the aircraft pitched up hitting the runway surface with the tail first, then the main landing gear, the nose rotated down until the nose gear impacted the runway and collapsed.

38 seconds after the nose gear had first indicated airborne the aircraft stopped at the left side of the runway, the crew advised ATC they had rejected takeoff and were evacuating the aircraft.
They forgot to input a temperature value required for the aircraft to calculate its own takeoff parameters and overrode the warning, so at 86 knots the aircraft basically told them to gently caress off and reject the takeoff. The pilot chose not to, and because there was no performance data computed and displayed for him, rotated early and over-aggressively, resulting in a tail strike and difficulty getting airborne. The pilot chose to reject the takeoff at this point, but overcompensated while pushing the nose down and slammed it down onto the runway, then bounced it back up into the air, at which point the entire aircraft briefly became airborne, after power to the engines had already been cut to idle. The pilot again over-compensated and pushed the aircraft down onto the runway hard enough to collapse the nose gear. The combined damage totaled a 15 year old airplane.

*The "retard" callout means to reduce engine power by "retarding" the throttles.

It sounds to me like the airplane was perfectly able to fly (the tailstrike happened during the abort) so I really don't see why the captain tried an abort during rotation in a situation where just setting full power (if it was a reduced power takeoff) and holding pitch would have resulted in nothing more serious than a longer takeoff roll.

I understand that the airplane would have been throwing all kinds of ECAM messages at the crew, but unless both engines blew up or a wing fell off, dealing with the problem in the air is always a better idea than trying an abort past V1.
