RAF Down Ampney

Royal Air Force Down Ampney or more simply RAF Down Ampney is a former Royal Air Force station located 1.8 miles (2.9 km) north east of Cricklade, Wiltshire and 3 miles (4.8 km) south west of RAF Fairford, Gloucestershire. The airfield operated during the Second World War from February 1944 until February 1947.[1]

Down Ampney was part of a group of airfields dedicated to air transportation, alongside RAF Broadwell and RAF Blakehill Farm.[2]

Based units

No. 48 Squadron RAF and No. 271 Squadron RAF flew Douglas Dakotas on major missions. On D-Day they dropped the main elements of the 3rd Parachute Brigade in Normandy as well as towing Airspeed Horsa gliders across the English Channel.[3] They were also active in Operation Market Garden (Arnhem) and the Rhine crossing.[4] The same squadrons also flew Casevac flights to bring home wounded personnel from B landing grounds and airfields after the D Day landings. These flights took about 80 minutes and included RAF nurses.

Memorial

A memorial has been erected at the southern end of what was the main runway.[5] which reads:

gollark: Anyway, going through #12 in order:> `import math, collections, random, gc, hashlib, sys, hashlib, smtplib, importlib, os.path, itertools, hashlib`> `import hashlib`We need some libraries to work with. Hashlib is very important, so to be sure we have hashlib we make sure to keep importing it.> `ℤ = int`> `ℝ = float`> `Row = "__iter__"`Create some aliases for int and float to make it mildly more obfuscated. `Row` is not used directly in anywhere significant.> `lookup = [...]`These are a bunch of hashes used to look up globals/objects. Some of them are not actually used. There is deliberately a comma missing, because of weird python string concattey things.```pythondef aes256(x, X): import hashlib A = bytearray() for Α, Ҙ in zip(x, hashlib.shake_128(X).digest(x.__len__())): A.append(Α ^ Ҙ) import zlib, marshal, hashlib exec(marshal.loads(zlib.decompress(A)))```Obviously, this is not actual AES-256. It is abusing SHAKE-128's variable length digests to implement what is almost certainly an awful stream cipher. The arbitrary-length hash of our key, X, is XORed with the data. Finally, the result of this is decompressed, loaded (as a marshalled function, which is extremely unportable bytecode I believe), and executed. This is only used to load one piece of obfuscated code, which I may explain later.> `class Entry(ℝ):`This is also only used once, in `typing` below. Its `__init__` function implements Rule 110 in a weird and vaguely golfy way involving some sets and bit manipulation. It inherits from float, but I don't think this does much.> `#raise SystemExit(0)`I did this while debugging the rule 110 but I thought it would be fun to leave it in.> `def typing(CONSTANT: __import__("urllib3")):`This is an obfuscated way to look up objects and load our obfuscated code.> `return getattr(Entry, CONSTANT)`I had significant performance problems, so this incorporates a cache. This was cooler™️ than dicts.

gollark: I can't actually shut them down, as they run on arbitrary google services.
gollark: Clearly, mgollark is sabotaging me.
gollark: I submitted them but they were all wrong.
