Not many modern planes use a twin vertical tail, in addition to what has already been mentioned...

They tend to fly in formation.

Maybe an X83?

Can't be Rutan's Boomerang. You'd know if you saw it.

Yeah, the Electra comes closest in appearance, I think, but still doesn't explain the wing.  Or the turboprop.

I kept turning up A10s when searching for twin-tail 2-engined low-wing aircraft, and it perfectly meets the criteria right down to the dihedral on the outer wing sections only, except for the engine type and location...

Nope.  Conventional single fuselage, twin wing-mounted engines, and a twin vertical stabilizer tail.

Was there an air show in the area? Could be a Commemorative/confederate air force bird. 

I believe they were probably inbound from the Hampton Roads area, and they do have airshows at Langley, but I couldn't find anything that would have suggested they had one last weekend.

No twin tail or twin engine turboprop but everybody (1988RedT2 excluded) swears it's one of these when they don't know so...

I don't know, I think you might be on drugs.

It's the dihedral thing that is stumping me, so I am just going to post a pic of a plane I saw recently that is quite bizarre:

Hey, that's cool.  Definitely not that plane, and there were two of them.  But time and location are close.  I was just SE of Kingsland Road on Hoke Brady Road.   Planes were flying more or less North, and it was very close to noon, probably just before noon, but only by minutes.

Just putting in 2 props and a B24 type tail doesn't give many options, and none like what you are describing.

So same flight was right there at 11:42 also going north, full path going out and around Cape Charles. My guess is the actual plane isn't in their lookup table and flying military they probably only had one set for multiple planes (some don't even show up I know).

The beech 18's i knew of had usually been swapped to turboprop over the old radial long ago.  One of my former customers had 2 beech 18's. One was still radial and amazing to see and hear.  
 

these were mosquito control planes that i was around. 

Anyone mention ov-10 warthogs yet?

Not a Piaggio P.180 Avanti, because you would know the distinct sound they make.

So the turboprop-swapped Beechcraft 18 or a Volpar Turboliner (which seems to be the same thing with a rebrand) look like the best match.

Yeah, I think I'm sold on the Volpar Turboliner.  Checks all the boxes.  Even seems to have a bit of an upward bend to the wing.

Interesting.  I am not thinking that is what I was seeing since it looks a bit more like a Lockheed than a Beach after conversion.  I do wonder about the wing spar on those though, not sure that was part of the modification:

The wing spar of the Model 18 was fabricated by welding an assembly of tubular steel. The configuration of the tubes in combination with drilled holes from aftermarket STC modifications on some of these aircraft have allowed the spar to become susceptible to corrosion and cracking while in service.[25] This prompted the FAA to issue an Airworthiness Directive in 1975, mandating the fitting of a spar strap to some Model 18s. This led, in turn, to the retirement of a large number of STC-modified Model 18s when owners determined the aircraft were worth less than the cost of the modifications. The corrosion on unmodified spars was not a problem; it occurred due to the additional exposed surface area created through the STC hole-drilling process. Further requirements have been mandated by the FAA and other national airworthiness authorities, including regular removal of the spar strap to allow the strap to be checked for cracks and corrosion and the spar to be X-rayed. In Australia, the airworthiness authority has placed a life limit on the airframe, beyond which aircraft are not allowed to fly.[26][27][28]

The plane does have an interesting history though:

Beech 18s were used extensively by Air America during the Vietnam War; initially more-or-less standard ex-military C-45 examples were used, but then the airline had 12 aircraft modified by Conrad Conversions in 1963 and 1964 to increase performance and load-carrying capacity. The modified aircraft were known as Conrad Ten-Twos, as the maximum takeoff weight (MTOW) was increased to 10,200 lb (4,600 kg).[23][24] The increase was achieved by several airframe modifications, including increased horizontal stabilizer angle-of-incidence, redesigned undercarriage doors, and aerodynamically improved wingtips. Air America then had Volpar convert 14 aircraft to turboprop power, fitted with Garrett AiResearch TPE-331 engines; modified aircraft were called Volpar Turbo Beeches, and also had a further increase in MTOW to 10,286 lb (4,666 kg).[23]

I finally got a decent shot of a plan that flies over my house occasionally.   I know what it is, and it's pretty unique.  Anyone want to guess (should be pretty easy if you have seen one before).  As to what is on the pylons... shhhhh......
