I have just added this to the map of places to fly your drone at Drone Scene:

When Sapperton Tunnel on the Thames & Severn Canal opened in 1789 it was the longest canal tunnel ever constructed in the United Kingdom at 2.17 miles (3.49km) in length. Today it is the third longest.
Construction started in 1783 and the first boat passed through in April 1789. The last commercial traffic to use the tunnel was in May, 1911.
As early as 1916, roof falls made the tunnel impassable to normal boat traffic.
Today Sapperton Tunnel remains impassable with a number of significant roof falls, and a complete blockage near the Sapperton end.
Length: 3,490m or 2.17 miles (3,817 yards or 173.5 chains)
Nominal width: 4.4m (14ft 4in) height: 4.7m (15ft 4in)
Maximum height of overburden: 66m (216ft)
(The distance between the tunnel roof and the surface ground level above.)
Distance from Wallbridge (Stroud): 7.5 route miles (12km)
Canal ascent from Wallbridge: 73.5m (241ft)
The tunnel is on the summit (highest level) of the canal which is about 111m (360ft) above mean sea level.
Tunnel entrances: Coates (east) & Daneway (west), both in Gloucestershire (UK)
