The Problem
Critical capacity, cost, and environmental challenges in middle-mile logistics
The global logistics industry is experiencing unprecedented strain as e-commerce growth and just-in-time delivery demands continue to surge. This growth has exposed significant inefficiencies in traditional transportation networks, leading many retailers to establish their own middle-mile operations: a stopgap solution that ultimately reduces overall network efficiency compared to consolidated operations. The dramatic increase in shipping costs relative to demand over the past 15 years points to substantial supply-side bottlenecks in the industry.
The cost of freight transportation has increased significantly more than demand, air freight even more drastically.

Infrastructure: These capacity constraints stem from fundamental infrastructure limitations and operational challenges. Congested roadways and airports, combined with persistent shortages of drivers and pilots, create hard limits on system throughput. Traditional solutions like infrastructure expansion are increasingly untenable – both financially and politically. The I-10 to I-15 Interchange project illustrates this challenge: an 11-mile road expansion providing just 20 years of capacity growth has taken 15 years to complete at a cost exceeding $1 billion. With hundreds of similar bottlenecks across the US transportation network, infrastructure expansion alone cannot meet growing demand.
Emissions: The environmental impact of middle-mile freight compounds these challenges. This sector currently accounts for approximately 7% of global carbon emissions, with projections showing emissions doubling by 2050 without radical technological intervention. Meeting EPA's 2050 emissions targets requires near-complete decarbonization of the freight sector : a daunting task given current technologies. Zero-emission alternatives face significant hurdles in range and payload capacity, making them economically challenging. Additionally, the limited supply of sustainable energy sources and battery materials, combined with 20-30 year vehicle lifecycles, necessitates immediate action.
Regional Air Freight: A microcosm
Regional parcel air freight, the movement of smaller payloads between hub and spoke airports, represents a particularly acute example of these challenges. Despite covering relatively short distances, this segment constitutes the majority of express freight delivery costs according to UPS executives. These high costs force excessive package consolidation at major hubs, increasing total travel distances. The environmental impact is equally concerning: while handling just 0.003% of US freight tonnage, regional air freight produces 0.25% of freight industry CO2 emissions: a staggering 73 times more CO2 per ton than the industry average.
To get an express parcel from Savannah, GA to Burlington, VT with current networks it takes 4 flights for a total of 1360 nm in the air. The direct flight would be 830 nm, not much more than half.
This confluence of capacity constraints, environmental imperatives, and economic inefficiencies demands a new approach: one that circumvents traditional infrastructure and manpower bottlenecks while dramatically reducing energy consumption.
