AAAAARGH!
OK, here are some explanations:
30 degrees - this could refer to the roll, pitch or flaps angle, I think it refers to the pitch
stall - A sudden lost of lift caused by a disruption of the normal flow of air over the upper surface of the wing. This occurs when the wing's angle of attack (angle between the wing and the oncoming air) reaches a critical value (critical angle of attack). Stall speed is the speed at which a plane enters in a stall under certain conditions (which is determined by pitch, thrust, bank, weight, flaps etc.)
beacon - A station that transmits one-way signals for the purpose of navigation
warning sound - This is the stall warning
push through that band of rain - Commercial airplanes mustn't fly through thunderstorm clouds
five miles out - 5 nautical miles from the airport (in aviation, nautical miles are used)
heading - The direction in which the aircraft is pointed, referenced to the magnetic north. This doesn't always correspond to the path of the aircraft over the ground (because of winds)
number 1, anticipating - At an airport aircrafts must fly in certain patterns assigned by the ATC (air traffic controller) to avoid collisions and they will land in a certain order, usually in the order they arrived in the airspace. Number 1 is the next aircraft that will land. ATC can give priority an aircraft in emergency situation.
mayday - The international call for help (from the French m'aidez). This is the voice transmission equivalent to SOS.
GMOVJ - This is the plane's registration number, the first letter (G) tells that the plane is from the UK. In aviation there are certain words for the letters of the alphabet (Alpha, Bravo, Charlie, Delta, Echo...) so GMOVJ is read Golf Mike Oscar Victor Juliet.
IMC - Instrument Meteorological Conditions, weather conditions that require IFR (instrument flying rules) in a controlled airspace, this generally means ceiling is less than FL10 (300 m) and visibility is less than 3 nm.
CU NIMB - Cumulonimbus clouds; dense, vertical cloud formations that produce rain or thunderstorm and heavy turbulence. Cumulus means 'heap' and nimbus means 'rain cloud' in Latin. Like all cumuliform clouds, CU NIMB forms in unstable air and they can extend well in the stratosphere.
icing - A very dangerous phenomena when ice is collecting on the upper surface of the wings and tail, modifying their shape and so increasing stall speed
squawk - To squawk means to set a number on the transponder. The transponder is an airborne transmitter-receiver that receives signals from air traffic control (ATC) and replies with a four-number identification code (squawk) set by the pilot, the numbers ranging from 1 to 7. This code is used to identify an aircraft on the ATC's radar display. Under IFR (instrument flying rules) the ATC assigns transponder codes to aircrafts. There are special squawk codes: 1200 for VFR, 7500 for hijacking, 7600 for lost radio communication and 7700 for emergency. Squawk emergency would meen set the transponder to 7700.
lost in static - this means the radio signal is breaking up
automatic - When radio communication is lost, the pilot has to use the ADF (Automatic Direction Finder) which receives signals from non-directional beacons (NDBs), this is 'automatic'
Beech 18 - one of the most adaptable and versatile twin-engined aircraft ever built. The type first flew in 1937 and orders for military versions were placed in 1941 with a total of 5024 being delivered during the war. Its two Pratt&Whitney radial engines deliver 450 hp. Take-off weight is 3400 kg, ceiling is FL270 (8200 m), range is 1200 nm, max. speed 220 kts.
