The 1-11 engines, as perhaps are all large jet engines, were started by air. This can be taken from the APU or a ground source.
You pressed the start switch on a 1-11 and it opened the air valve in the engine cowling to allow the high pressure air to the engine start system. Only on the 1-11 the said valve was notorious for sticking, and this could be cured by giving it a ‘whack’. Not hard enough to damage it, but hard enough to encourage the valve to open. I well remember being the captain of a DAN 1-11 when the valve didn’t open in Toulouse one afternoon. I left the F/O in the jet, stationed a member to the handling crew at the front to give the F/O the thumbs up when I was ready, and then hitting the valve with the rubber bit of the fire axe – all watched by some passengers looking out of the terminal window and the rear of the aeroplane. It was certainly in the stub wing, and it was very noisy closing the the cowling up after the start. I don't remember any rod to twist, but it was over 25 years ago. Lets see 25 multiply by 365 and then by 2 pints a night and the memory may not be that sharp! Hey ho – interesting times. |
Thanks guys! Excellent. I thought the engineers were hitting something but from my seat in GMC it was difficult to see, even with binoculars! They seemed to use the aircraft engineers equivalent of a panel beating hammer.
On the Monarch aicraft starting issue ..The Boeing 720B. I remember that on occasion they were started by an air start compressor that was connected by some sort of trunking to the aircraft belly? I do remember an incident when the ‘trunking’ either ripped or the coupling to the aircraft became detached leaving it snaking around like a demented Python. However, my personal favourite was the spectacular flame from each Proteus as a Bristol Britannia started. Sadly something that we won’t see again. |
As one of the Airline Engineering guys who applied a ‘calculated tap’ to the Spey I can tell you that it was the CSDS PRV that we ‘tapped’. The mechanism was prone to sticking. I have seen various implements used, including a chock. The start up was always a waiting game to see if the engine started or the CSDS Drive sheared. Prior to this happening you would hear a ‘zing’ as it sheared leaving you in no doubt what the problem was.

The Air Start unit used to start the 720 plugged into the l/h fuselage just fwd of the wing. This noisy beast was also very heavy. Towing it slowly was advisable as it took some stopping. On the flight deck one day the aircraft was jolted violently to the left. Rushing downstairs we discovered that an air start had disconnected from the tow vehicle when being positioned and embedded itself in the rear fuselage by the aft cargo hold. Morning departures for up to 6 720 normally parked next to each other within a few minutes of each other was always exciting. Lots of noise, movement and......oh the memories.

LTNman thanks for posting that photo of the Monarch 1-11 framed by B720 tails, any idea which winter it was taken in?
Love the photo by the way. |
I remember that day, two on "The Pond" the third left on the Alpha taxiway and passengers left for hours. Only Bravo in use after that though not much else got in due to the number of EGKK diverts.

quite possibly early Jan '79 following snowfall on New Years Eve 31/12/78 which hit Gatwick and Heathrow ahead of Luton

Probably both LTMan. No Thameslink or M25 in those days. Down M1 to the North Circular, then over Kew Bridge and wind your way across to the A217 to Reigate and on to Gatwick. I remember a very nice Little Chef (when they were good) just before Gatwick that did a very nice breakfast served by a very good looking blonde lady. I digress. Coaches used to get pax back to Gatwick I suppose Seamarks, Richmonds and Crawley Luxury, the latter two still going strong.

That's them! I was going to dig out some pictures myself but mine would have been from the spectators enclosure. I had conned my dad in taking me up on a Sunday morning as I wasn't going up on my push bike.
RIP Dad, hope you are still enjoying your touch and goes on 24/06. |

Ah, these two then. I think some folk here have remarkable memories. Either that or extraordinary days at Luton are burned into peoples memories.
I was working a night shift (2000-0800) on 31/12/78. Management had struck a deal for us to start early at 1700 and finish after the last movement, which was the regular Sunday Austrian DC-9 STD 2150. Then everyone was expecting to go to a New Years Eve party. Temperature was already down to -5º when I arrived for my shift to be greeted by the sight of 4 diverted Dan Airs, a couple of Lufthansa 737's and the 2 Laker DC-10's on stands 16/17. It was dark, so I didn't realise taxiway Alpha was home to the 3rd Laker DC-10 and a Sterling Caravelle. A Lufthansa 727-200 and a Midland DC-9-14 had already departed after diverting in earlier. Snow moved in during the evening dropping the temperature down to -7º but the airport must have stayed open, with the Austrian managing to get in and out on time. Needless to say, with the ongoing situation and the threat of more diverted flights, no-one got away for their planned parties until after midnight, around 0100 in my case. |

Geminair 9G-ACE?

@LTNman (or anyone)
The old Spittlesea Hospital Main Building (now used by SixT) has to be the oldest original building on the site but what can you tell us about Hangar 24? I'd hazard a guess that it's very much the last man standing in term of oldest airport buildings. (there is/was a photo of it being built somewhere in this forum). Is it now a listed building? Was it of any significance? |

Here is a pic from 1938. Another hangar going up next to hangar 24 (was this hangar 22?) https://i.imgur.com/gRdjQgK.jpg |

I think the oldest hangars are the former Monarch hangars 7 & 8 but they gained height in the 60's but I don't know if they were rebuilt or just made taller. https://i.imgur.com/fCuqcmx.jpg?1 https://i.imgur.com/kDjk54U.jpg Hangar 24 is behind hangar 9 although I suspect all have been re-clad over the years. Hangars 7/8 were extended. |
I am intrigued as to the purpose of the 'second line' of hangars, being called 22, 24 etc. As they are away from the grass airfield line. Were they built for the construction of aircraft / components, rather than the storage of aeroplanes ? As they were no doubt called in those days

Geminair, another airline I'd forgotten... 9G-ACE was a regular at Gatwick.

Also worth noting is that the T2’s are clustered together rather than the standard practice of spreading the hangars around the airfield so they could not have been built for the RAF who did have a squadron based at the airfield for a short time. |
