Yamchun Fortress
Yamchun Fortress is located in the Pamir mountains at over 10000 feet asl, it was built in 3 century to protect the caravan of the Silk Road along the Wakhan Valley
Yamchun Fortress
Yamchun Fortress in the Pamir Mountains of Tajikistan is roughly 2,100 to 2,300 years old.
Timeline & Construction Phases
Initial Construction (3rd – 1st Century BCE): The earliest foundations of the citadel were built over two millennia ago, most likely under the Kushan Empire (or late Bactrian/Scythian influences in the region).
Perched high on a rocky ridge overlooking the Wakhan Valley and the Panj River (bordering modern Afghanistan), the fortress allowed guards to monitor trade along the Silk Road, collect taxes from passing caravans, and defend the valley against raiders. Its local Pamiri name, Zamr-i-Atash-Parast, translates to "Fortress of the Fire Worshippers," referencing the region's ancient Zoroastrian heritage prior to the arrival of Islam.
History made!
GE Aerospace announced today a new industry first to advance hybrid electric flight, demonstrating the viability of more electric aircraft engine systems for commercial aviation.
In collaboration with @NASAaero, @beta.aircraft, and @Boeing, GE Aerospace recently conducted the first hybrid electric flight above 30,000 feet, reaching the same altitude levels of passenger commercial aircraft.
The record-breaking test campaign was enabled by GE Aerospace's fully integrated, megawatt-class, and multi-kilovolt hybrid electric propulsion system developed through NASA's Electrified Powertrain Flight Demonstration (EPFD) project

reddit.comHigh speed Train MD (219mph)
This pilot project should start here in Maryland.
If we layout tracks following **I-97** down from Baltimore, sweeping onto **US-50 East**, crossing the **Chesapeake Bay Bridge**, and tracking Route 50 all the way down through Easton, Salisbury, and into Ocean City, the one-way distance stretches to about **125 miles**. For a round trip, that is a total of **250 miles**.
To make this realistic, we have to break the trip down into phases, assuming a top-tier train like a modified Shinkansen or Eurostar:
* **Acceleration / Deceleration:** The train needs time to ramp up to 219 mph leaving Baltimore, slow down for the Bay Bridge, ramp back up on the Eastern Shore, and slow down for the terminus.
* **The Bay Bridge Curve & Span:** High-speed trains must slow down significantly on tight curves and long over-water spans due to crosswinds and structural tracking limits. We will budget a restricted **90 mph** for a 6-mile stretch across the bridge and its approaches.
### The Round-Trip Timeline
A realistic, non-stop operational run looks like this:
- Baltimore to the Bay Bridge Approach
~24 miles
Leaving Penn Station, the train navigates the Baltimore tunnels and accelerates to its 219 mph cruising speed down the I-97/US-50 corridor.
Time: 8.5 minutes - Chesapeake Bay Bridge Crossing
~6 miles
The train decelerates smoothly to 90 mph to safely cross the suspension span, giving passengers a brief, sweeping view of the bay.
Time: 4 minutes - The Eastern Shore Sprint
~95 miles
Clearing Kent Island, the train punches back up to 219 mph, screaming parallel to Route 50 past Easton, over the Choptank River, through the Salisbury bypass, and straight to the coast.
Time: 27.5 minutes - Ocean City Arrival & Turnaround
Deceleration
The train brakes firmly as it approaches the Harry W. Kelley Memorial Bridge structure, coming to a full stop at a hypothetical terminal just outside downtown Ocean City.
Time: 2.5 minutes
### The Final Tally
* **One-Way Time:** \approx **43 minutes**
* **Total Round-Trip Travel Time:** \approx **1 ohour and 25 minutes**
** Even with the real-world routing and a major slowdown for the Bay Bridge, a round-trip commute that normally takes drivers 5 to 6 hours on a summer weekend shrinks to less than an hour and a half.
