And the front. Few plants in front of it and nobody will see it.

Now back at home again to finish off my sleeper retaining wall. The difference in level is only about a foot but we wanted something to last. The vertical posts go 4 foot deep into solid clay so no chance of this ever moving. :D

A drain runs underneath that takes water from further up the hill, past her driveway into a ditch. I was informed that there was also a electrical cable buried but that it would be roughly 2 feet underneath the drainage pipe. No surprise really that when I found the drain I also found the...

A quick job this morning. Customer called to report water bubbling up in front of her driveway. She lives in the village so it was only a 5 minute drive to get to her and start investigating.

The airspace over Europe is very busy and congested. On 28 June 2019 there were 37.228 flights in European airspace.

True but flying a plane is more or less simply following a line through the sky. It is fairly easy to get a car to just follow the satnav if it wasn’t for the other nutters on the road. Up in the sky you don’t have to worry about kids jumping out from behind parked airplanes. :D

Pre covid the skies were very busy and you could quite happily fly at the same flight level on an intersecting course. Normally Air Traffic Control (ATC) would instruct one (or both) aircraft to turn 10 or 15 degrees to the left or right so that we safely pass. For opposite traffic we are...

Apologies Rick, I hadn’t seen your post. I will get to it now. :thumb2

Rick, have a look at the Antonov AN225. That is a real beast designed to carry the Russian space shuttle on its back. It can take up to 250 tonne of cargo internally or 200 tonne on top of the fuselage. https://en.wikipedia.org/wiki/Antonov_An-225_Mriya

The AN124 is one of the biggest cargo aircraft. It can take up to 150 tonne of cargo and is designed to operate from unimproved (dirt) runways. It is designed and built in the Ukraine when this was still part of the USSR. https://en.wikipedia.org/wiki/Antonov_An-124_Ruslan We use them quite...

Nicely done Rick. That is now made to last.

A topic which is quite active and very interesting on other forums, I thought we may as well give it a go here. Today I went to Lviv in the Ukraine. Quick trip out and back. While we were on the ground an Antonov AN124 landed and was in the process of being loaded by the Ukrainian army as we...

Looks good Elty! That is some welding I can only dream off.

I can pick up a tube of KY jelly next time I go shopping and send it to Zac if that helps your relationship along. :D

You got me worried now! :eek:

That how I understand it Rick. The force is absorbed by the impact, hence why a softer log has a lower impact force. The energy that the blade carries when it reaches the top of the log is the same as it falls from the same height. You could potentially fill the cylinder with concrete or heavy...

Then the calculation for a penetration depth of 0.01Mt. This generates an impact force of 88200N or 8987.58Kg. The drawing below the calculation (blue object) does explain whythere is a difference in impact force between the two calculations. It all depends on the amount of penetration. I don’t...

Rick, I am no mathematics professor so I had to resort to the internet. I get slightly different values then you get. This is the calculation with an impact of 0.001Mt producing an impact force of 8820N. 1N (Newton) is 0.1019Kg. 8820 x 0.1019 = 898.75kg impact force.

Well spotted Banshee! Been flying for over 20 years. Whilst I enjoy doing it, I prefer the engineering side. Sitting on my backside for 12 hours is not my idea of fun. However as my better half says, I am not your typical pilot. You won’t find a set of golf clubs in our house. :D I am at my...

That particular one is an Airbus A320 but I also fly the Airbus A350. Unfortunately life has changed since Covid hit. I used to fly part time and work as an engineer on my off blocks. With the impact of Covid I have now temporarily (hopefully) gone back to only flying.
